Harvard professor Avi Loeb believes he may have found fragments of alien technology from a meteor that landed in the waters off of Papua, New Guinea in 2014. CBS News reports: Loeb and his team just brought the materials back to Harvard for analysis. The U.S. Space Command confirmed with almost near certainty, 99.999%, that the material came from another solar system. The government gave Loeb a 10 km (6.2 mile) radius of where it may have landed. "That is where the fireball took place, and the government detected it from the Department of Defense. It's a very big area, the size of Boston, so we wanted to pin it down," said Loeb. "We figured the distance of the fireball based off the time delay between the arrival of blast wave, the boom of explosion, and the light that arrived quickly."

Their calculations allowed them to chart the potential path of the meteor. Those calculations happened to carve a path right through the same projected 10 km range that came from the U.S. government. Loeb and his crew took a boat called the Silver Star out to the area. The ship took numerous passes along and around the meteor's projected path. Researchers combed the ocean floor by attaching a sled full of magnets to their boat. "We found ten spherules. These are almost perfect spheres, or metallic marbles. When you look at them through a microscope, they look very distinct from the background," explained Loeb, "They have colors of gold, blue, brown, and some of them resemble a miniature of the Earth."

An analysis of the composition showed that the spherules are made of 84% iron, 8% silicon, 4% magnesium, and 2% titanium, plus trace elements. They are sub-millimeter in size. The crew found 50 of them in total. "It has material strength that is tougher than all space rock that were seen before, and catalogued by NASA," added Loeb, "We calculated its speed outside the solar system. It was 60 km per second, faster than 95% of all stars in the vicinity of the sun. The fact that it was made of materials tougher than even iron meteorites, and moving faster than 95% of all stars in the vicinity of the sun, suggested potentially it could be a spacecraft from another civilization or some technological gadget." He likens the situation to any of the Voyager spacecrafts launched by NASA.

The UN secretary general has said that "climate change is out of control," as an unofficial analysis of data showed that average world temperatures in the seven days to Wednesday were the hottest week on record. From a report: "If we persist in delaying key measures that are needed, I think we are moving into a catastrophic situation, as the last two records in temperature demonstrates," Antonio Guterres said, referring to the world temperature records broken on Monday and Tuesday. The average global air temperature was 17.18C (62.9F) on Tuesday, according to data collated by the US National Centers for Environmental Prediction (NCEP), surpassing the record 17.01C reached on Monday. For the seven-day period ending Wednesday, the daily average temperature was .04C (.08F) higher than any week in 44 years of record-keeping, according to the University of Maine's Climate Reanalyzer data. That metric showed that Earth's average temperature on Wednesday remained at the record high of 17.18C.

Climate Reanalyzer uses data from the NCEP climate forecast system to provide a time series of daily mean two-metre air temperature, based on readings from surface, air balloon and satellite observations. The US National Oceanic and Atmospheric Administration (NOAA), whose figures are considered the gold standard in climate data, said on Thursday it could not validate the unofficial numbers. It noted that the reanalyzer uses model output data, which it called "not suitable" as substitutes for actual temperatures and climate records. The NOAA monitors global temperatures and records on a monthly and an annual basis, not daily.

Stephen Clark writes via Ars Technica: When India's ambassador to the US signed up his country to the Artemis Accords last month, it signaled the world's most populous nation -- with a growing prowess in spaceflight -- could be turning toward the United States as a partner in space exploration. India became the 27th country to sign the Artemis Accords, a non-binding set of principles among like-minded nations guiding a vision for peaceful and transparent exploration of space. The accords cover the international registration of human-made space objects, the open release of scientific data, and an agreement for nations not to claim territory on the Moon or other planetary bodies, among other tenets.

Details about future cooperation between the US and India remain scarce. Nelson plans to travel to India later this year for meetings and discussions with Indian space officials. One objective of Nelson's trip will be to hammer out broad objectives for a "strategic framework" for human spaceflight cooperation. Despite the name of the Artemis Accords, there's no guarantee that India will play a significant role in NASA's Artemis program to return astronauts to the Moon and eventually send humans to Mars. "There's no implication of a signatory to the Artemis accords also being part of the Artemis program," Nelson told Ars.

But none of the other 26 signatories to the Artemis Accords -- a list that includes European space powers and Japan -- has their own human spaceflight program. India is developing a human-rated spacecraft called Gaganyaan that could be ready to fly people into low-Earth orbit in 2025, several years later than originally planned. "The fact that they are a nation that intends in the future to fly own their own astronauts, is that significant? The answer is yes," Nelson said. "I think it's of significance that a major country that's not considered aligned with the US (is) a signatory." "I've described India as a sleeping giant and one that is quickly awakening," Gold told Ars. "India is absolutely vital to global space development, and Artemis in particular, since the country is active with lunar programs, Martian programs, and now even human spaceflight." "Where India might fit into the Artemis program is still to be determined," writes Clark. "The partnership between the US and India in space could take a step forward next year with the flight of an Indian astronaut to the International Space Station. NASA has agreed to provide advanced training to Indian astronauts at the Johnson Space Center in Houston before a flight opportunity to the space station in low-Earth orbit."

India's space program has "held closer ties with Russia in the past," notes Clark. "Russia provided upper-stage engines for India's GSLV Mk.II rocket until India developed its own engine for the job. And four Indian astronauts slated for the Gaganyaan program completed more than a year of training at Russia's Gagarin Cosmonaut Training Center near Moscow in 2021, according to Indian media."

"Despite India's overture toward a closer relationship with NASA, the Asian power remains linked with Russia," adds Clark. "India still imports significant amounts of Russian oil and has not officially condemned Russia's invasion of Ukraine."

An anonymous reader quotes a report from the Associated Press: The planet's temperature spiked on Tuesday to its hottest day in decades and likely centuries, and Wednesday could become the third straight day Earth unofficially marks a record-breaking high. It's the latest in a series of climate-change extremes that alarm but don't surprise scientists. The globe's average temperature reached 62.9 degrees Fahrenheit (17.18 degrees Celsius) on Tuesday, according to the University of Maine's Climate Reanalyzer, a common tool based on satellite data, observations, and computer simulations and used by climate scientists for a glimpse of the world's condition. On Monday, the average temperature was 62.6 degrees Fahrenheit (17.01 degrees Celsius), setting a record that lasted only 24 hours.

University of Maine climate scientist Sean Birkle, creator of the Climate Reanalyzer, said the daily figures are unofficial but a useful snapshot of what's happening in a warming world. Think of it as the temperature of someone who's ill, he said: It tells you something might be wrong, but you need longer-term records to work like a doctor's exam for a complete picture. While the figures are not an official government record, "this is showing us an indication of where we are right now," said National Oceanic and Atmospheric Administration chief scientist Sarah Kapnick. And NOAA indicated it will take the figures into consideration for its official record calculations.

Even though the dataset used for the unofficial record goes back only to 1979, Kapnick said that given other data, the world is likely seeing the hottest day in "several hundred years that we've experienced." Scientists generally use much longer measurements -- months, years, decades -- to track the Earth's warming. But the daily highs are an indication that climate change is reaching uncharted territory.

JoeRobe writes: After 63 days of agonizing silence, NASA's Martian chopper finally phoned home. The Ingenuity helicopter reestablished communication with mission control on June 28, officially logging its 52nd flight as a success, NASA recently announced. The space agency lost contact with Ingenuity as the helicopter was descending towards the surface of the Red Planet following its most recent flight on April 26.

The reason behind the communication drop was that a hill was inconveniently positioned between Ingenuity and its rover pal Perseverance, preventing the Martian pair from communicating with one another. Ingenuity relies on Perseverance to deliver its messages to Earth, using shiny antennas to exchange data at about 100 kilobits per second. The data is routed from the Ingenuity-facing antenna to the rover's main computer before being transferred to Earth by way of an orbiting spacecraft.

A new article in the Washington Post reports that even internally, "Space Force officials are still debating its priorities, analysts say: Is it to support warfighters on the ground? Or should it focus primarily on protecting assets in space? Or both?"

In April, the Washington Post reported that space would likely be a key part of a Chinese invasion of Taiwan, and one possible Space Force counter-measure would "ensure that the United States avoids 'operational surprise,' by keeping track of other countries' satellites and movements in space while also being able to 'identify behaviors that become irresponsible or even hostile.'"

To address the possibility of enemies shooting down satellites, the Space Force is also "pivoting, relying on constellations of small satellites that can be easily replaced and, to an increasing degree, maneuver." That's just one example of how the Space Force intends to ensure the U.S. maintains "space superiority," as its leaders often say, to protect the satellites the Defense Department relies on for warnings of incoming missiles, steering precision-guided munitions and surveilling both friendly and hostile forces. It also could deter conflict in space — why strike a satellite if there are backups that would easily carry on the mission...?

[Maj. Gen. Stephen Purdy, the commander of the 45th Space Wing] gave a tour of some of the roles the Space Force could play, offering a glimpse into its future. Soldiers and Marines already pre-position supplies and equipment on the ground, he said. Could the Space Force start storing supplies in space and then fly them to hot spots on Earth as well? "In theory, we could have huge racks of stuff in orbit and then somebody can call those in, saying. 'I need X, Y, Z delivered to me now on this random island.' And then, boom, they shoot out and they parachute in and they land with GPS assistance," he said. "It's a fascinating thought exercise for emergency response — you know if a type of tidal wave or tsunami comes in and wipes out a whole area."

The military is also working to harness solar energy in space, and then beam it to ground stations. Could the Space Force use that technology to beam power to remote areas to support soldiers on the ground? Another idea: If the cadence of launches really does double or triple and the costs continue to come down, could the Space Force start using rockets to deliver cargo across the globe at a moment's notice? Soon there could be commercial space stations floating around in orbit. "Can we lease a room?" Purdy said. "Can we lease a module?"
A former vice chairman of the Joint Chiefs of Staff believes the U.S. Space Force is misunderstood — at least partly because much of what it does is classified. "We fundamentally need to normalize the classification," he tells the Washington Post, "so we can have a conversation with the public, with the American people."

"Black Swan events are hard-to-predict rare events that can significantly alter the course of our lives," begins a 2021 paper by a computer science professor at the University of California.

Now the Washington Post revisits that exploration of the possibility that "magnetic fields unleashed by a solar superstorm rip through Earth's magnetosphere, sending currents surging through human infrastructure." A widespread internet outage could, indeed, be brought on by a strong solar storm hitting Earth — a rare but very real event that has not yet happened in the digital age, experts say. When a solar storm known as the Carrington Event struck in 1859, telegraph lines sparked, operators were electrocuted and the northern lights descended to latitudes as low as Jamaica. A 1989 solar storm took out the Quebec power grid for hours. And in 2012, a storm just missed Earth.

As the sun, which has roughly 11-year cycles, enters a particularly active period known as the "solar maximum" in 2025, some are worried our interconnected world is not prepared.

Sangeetha Abdu Jyothi, a computer science professor at University of California at Irvine whose paper "Solar Superstorms: Planning for an Internet Apocalypse" has played a role in popularizing the term, started thinking about internet resilience when the coronavirus began to spread, and she realized how unprepared we were for a pandemic. Research on widespread internet failure was scant. "We've never experienced one of the extreme case events, and we don't know how our infrastructure would respond to it," Jyothi said. "Our failure testing doesn't even include such scenarios."

She notes that a severe solar storm is likely to affect large-scale infrastructure such as submarine communication cables, which could interrupt long-distance connectivity. If you have not lost power, you might have access to, say, a government website hosted locally, but reaching bigger websites, which could have data stored all over the place, might not be possible. The northern latitudes are also especially vulnerable to solar storms, and that's where a lot of internet infrastructure is concentrated. "This is not taken into account in our infrastructure deployment today at all," she said. Such outages could last for months, depending on the scale and how long it takes to repair the damage. The economic impact of just one day of lost connectivity in the United States alone is estimated to be more than $11 billion, according to the internet watcher NetBlocks.

Still, Jyothi says she has felt bad for using the term "internet apocalypse" in her paper. There's not much ordinary people can do to prepare for such a phenomenon; it falls on governments and companies. And the paper "just got too much attention," she said.
"Astrophysicists estimate the likelihood of a solar storm of sufficient strength to cause catastrophic disruption occurring within the next decade to be 1.6 to 12%," the paper concludes. (It also notes that the U.S. has a higher risk for a disconnection than Asia.)

"Paying attention to this threat and planning defenses against it, like our preliminary effort in this paper, is critical for the long-term resilience of the Internet."

"The European Space Agency's Euclid space telescope launched at 11:12 a.m. ET Saturday," reports CNN, "aboard a SpaceX Falcon 9 rocket from Florida's Cape Canaveral Space Force Station.

CNN is calling it "a mission designed to unravel some of the greatest mysteries of the universe." The 1.2-meter-diameter (4-foot-diameter) telescope has set off on a monthlong journey to its orbital destination of the sun-Earth Lagrange point L2, which is nearly 1 million miles (1.6 million kilometers) away from Earth and also home to NASA's James Webb Space Telescope... After arriving at orbit, Euclid will spend two months testing and calibrating its instruments — a visible light camera and a near-infrared camera/spectrometer — before surveying one-third of the sky for the next six years. Euclid's primary goal is to observe the "dark side" of the universe, including dark matter and dark energy. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Meanwhile, dark energy is a mysterious force thought to play a role in the accelerating expansion of the universe.

In the 1920s, astronomers Georges Lemaître and Edwin Hubble discovered that the universe has been expanding since its birth 13.8 billion years ago. But research that began in the 1990s has shown that something sparked an acceleration of the universe's expansion about 6 billion years ago, and the cause remains a mystery. Unlocking the true nature of dark energy and dark matter could help astronomers understand what the universe is made of, how its expansion has changed over time, and if there is more to understanding gravity than meets the eye... Euclid is designed to create the largest and most accurate three-dimensional map of the universe, observing billions of galaxies that stretch 10 billion light-years away to reveal how matter may have been stretched and pulled apart by dark energy over time. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years...

The telescope's image quality will be four times sharper than those of ground-based sky surveys. Euclid's wide perspective can also record data from a part of the sky 100 times bigger than what Webb's camera can capture. During its observations, the telescope will create a catalog of 1.5 billion galaxies and the stars within them, creating a treasure trove of data for astronomers that includes each galaxy's shape, mass and number of stars created per year. Euclid's ability to see in near-infrared light could also reveal previously unseen objects in our own Milky Way galaxy, such as brown dwarfs and ultra-cool stars.

In May 2027, Euclid will be joined in orbit by the Nancy Grace Roman Telescope. The two missions will overlap in their study of cosmic acceleration as they both create three-dimensional maps of the universe...Roman will study one-twentieth of the sky in infrared light, allowing for much more depth and precision. The Roman telescope will peer back to when the universe was just 2 billion years old, picking out fainter galaxies than Euclid can see.
CNN points out that "While primarily an ESA mission, the telescope includes contributions from NASA and more than 2,000 scientists across 13 European countries, the United States, Canada and Japan."

And they also note this statement from Jason Rhodes, a senior research scientist at NASA's Jet Propulsion Laboratory. "With these upcoming telescopes, we will measure dark energy in different ways and with far more precision than previously achievable, opening up a new era of exploration into this mystery."

From NASA's announcement: Scientists are unsure whether the universe's accelerated expansion is caused by an additional energy component, or whether it signals that our understanding of gravity needs to be changed in some way. Astronomers will use Roman and Euclid to test both theories at the same time, and scientists expect both missions to uncover important information about the underlying workings of the universe...

Less concentrated mass, like clumps of dark matter, can create more subtle effects. By studying these smaller distortions, Roman and Euclid will each create a 3D dark matter map... Tallying up the universe's dark matter across cosmic time will help scientists better understand the push-and-pull feeding into cosmic acceleration.
SpaceX tweeted footage of the telescope's takeoff, and the successful landing of their Falcon 9's first stage on a droneship called A Shortfall of Gravitas.

Supermassive black holes all over the universe are merging, a fate that will eventually come for the black hole at the center of our galaxy. From a report: These mysterious cosmic structures at the heart of nearly every galaxy consume light and matter and are impossible to glimpse with traditional telescopes. But now, for the first time, astrophysicists have gathered knowledge directly from these titans, in the form of gravitational waves that ripple through space and time. What they learned suggests that the population of massive black hole pairs that are merging numbers in the hundreds of thousands -- perhaps even millions.

The gravitational waves from these mergers are all contributing to an underlying background hum of the universe that researchers can detect from Earth. The findings, from a collaboration of more than 100 scientists, help confirm what will one day happen to the supermassive black hole at our galaxy's center, known as Sagittarius A*, as it crashes into the black hole at the heart of the Andromeda galaxy. "The Milky Way galaxy is on a collision course with the Andromeda galaxy, and in about 4.5 billion years, the two galaxies are set to merge," said Joseph Simon, a University of Colorado, Boulder, astrophysicist and a member of the North American Nanohertz Observatory for Gravitational Waves, or Nanograv, which helped lead the new work with support from the National Science Foundation.

That merger, he said, will eventually result in the black hole at the center of Andromeda and Sagittarius A* sinking into the center of the newly combined galaxy and forming what is known as a binary system. The results were announced in a series of papers published Wednesday in the Astrophysical Journal Letters. "Before now, we didn't even know if supermassive black holes merged, and now we have evidence that hundreds of thousands of them are merging," said Chiara Mingarelli, a Yale University astrophysicist and a member of Nanograv. The new work could answer questions such as how these black holes grow, and how often their host galaxies merge, the researchers said.

The exoplanet 8 Ursae Minoris b should not exist. It orbits its host star at just half the Earth-Sun distance, and by all indications, the star should have gone through a phase in which it bloated up enough to engulf that entire orbit and then some. Yet 8 Ursae Minoris b definitely appears to exist. From a report: There is a handful of potential explanations, none of them especially likely. The people who discovered the planet are suggesting that it survived because its host star got distracted by swallowing a white dwarf instead. 8 Ursae Minoris b was discovered using the radial velocity method, which watches for changes in a star's light that occur as planets tug the star back and forth as they orbit. This tugging creates a blue shift in the light when the planet is pulling the star in the direction of Earth and a red shift when the star is pulled away from Earth.

But the planet is unlikely to be tugging the star directly toward Earth, so we tend to only measure the component of the star's motion that's in our direction. We'd see the same apparent motion of the star if a light planet's orbit was oriented directly toward Earth or a very heavy planet that has a relatively skewed orbit. At best, radial velocity measurements give us an estimate of the minimum mass of the planet; it could potentially be larger. So we know that, at minimum, 8 Ursae Minoris b is a big planet, at over 1.6 times the mass of Jupiter. It also resides close to its host star, completing a full orbit in just 93 days. That places it at half an Astronomical Unit (AU, the typical distance between Earth and the Sun) from its star.

Observations also hint at a second body orbiting the star at least five AU. The evidence for that is weak given the current data, but it may have a significant role in shaping the system. On its own, there's nothing especially unusual about the 8 Ursae Minoris exosolar system. Where things get weird is when you consider the star at the center of the system.

An anonymous reader shares a report: It's surprisingly easy for someone to mess with the makeup of Earth's atmosphere, regardless of the consequences that could have for our planet. Now, as part of its plans to address security risks posed by climate change, the European Union is calling for talks on a potential international framework on how to treat deliberately atmosphere-altering technologies, AKA geoengineering.

The issue is that scientists aren't quite sure how much good that would do or whether geoengineering might inadvertently trigger new problems. That's why the European Commission says the world needs to start thinking about rules on geoengineering. Without them, climate vigilantes could decide to go ahead with their experiments without any oversight or accountability. In fact, that's already started to happen, albeit on a small scale.

An anonymous reader quotes a report from The Hill: Asked June 26 about allegations of secret UFO retrieval and reverse-engineering programs, Senate Intelligence Committee Vice Chairman Marco Rubio (R-Fla.) made several stunning statements. In an exclusive interview, Rubio told NewsNation Washington correspondent Joe Khalil that multiple individuals with "very high clearances and high positions within our government" "have come forward to share" "first-hand" UFO-related claims "beyond the realm of what [the Senate Intelligence Committee] has ever dealt with."

Rubio's comments provide context for a bipartisan provision adopted unanimously by the Senate Intelligence Committee, which would immediately halt funding for any secret government or contractor efforts to retrieve and reverse-engineer craft of "non-earth" or "exotic" origin. This extraordinary language added to the Senate version of the Intelligence authorization bill mirrors and adds significant credibility to a whistleblower's recent, stunning allegations that a clandestine, decades-long effort to recover, analyze and exploit objects of "non-human" origin has been operating illegally without congressional oversight.

Additionally, the bill instructs individuals with knowledge of such activities to disclose all relevant information and grants legal immunity if the information is reported appropriately within a defined timeframe. Moreover, nearly 20 pages of the legislation appear to directly address recent events by enhancing a raft of legal protections for whistleblowers while also permitting such individuals to contact Congress directly. Researcher and congressional expert Douglas Johnson first reported on and analyzed the remarkable bill language, which, if it passes the House, could become law this calendar year.

Apple has uploaded the entire first episode of its sci-fi series "Silo" to Twitter, allowing anyone there to watch the opening installment for free. Engadget reports: Silo is based on the science fiction novel Wool by American author Hugh Howey. It takes place on a post-apocalyptic version of Earth, where what remains of humanity is confined to the Silo, a 144-story underground bunker that serves as a self-sufficient underground community. The citizens are told that the world outside the Silo is perilous, but questions arise about what truly lies beyond. It's a clever premise that allows showrunner Graham Yost to explore the book's themes about truth vs. fiction and information as power. Apple has reportedly renewed the series for a second season. You can watch the full episode on Twitter here.

An ancient Nevada lakebed could become a vast source of the lithium used in electric car batteries, reports the Associated Press. But "NASA says the same site — flat as a tabletop and undisturbed like none other in the Western Hemisphere — is indispensable for calibrating the razor-sharp measurements of hundreds of satellites orbiting overhead." At the space agency's request, the U.S. Bureau of Land Management has agreed to withdraw 36 square miles (92 square kilometers) of the eastern Nevada terrain from its inventory of federal lands open to potential mineral exploration and mining. NASA says the long, flat piece of land above the untapped lithium deposit in Nevada's Railroad Valley has been used for nearly three decades to get measurements just right to keep satellites and their applications functioning properly. "No other location in the United States is suitable for this purpose," the Bureau of Land Management concluded in April after receiving NASA's input on the tract 250 miles (400 kilometers) northeast of Las Vegas...

In Railroad Valley, satellite calculations are critical to gathering information beamed from space with widespread applications from weather forecasting to national security, agricultural outlooks and natural disasters, according to NASA, which said the satellites "provide vital and often time-critical information touching every aspect of life on Earth." That increasingly includes certifying measurements related to climate change. Thus the Nevada desert paradox, critics say. Although lithium is the main ingredient in batteries for electric vehicles key to reducing greenhouse gases, in this case the metal is buried beneath land NASA says must remain undisturbed to certify the accuracy of satellites monitoring Earth's warming atmosphere...

The area's unchanged nature has allowed NASA to establish a long record of images of the undisturbed topography to assist precise measurement of distances using the travel time of radio signals and assure "absolute radiometric calibration" of sensors on board satellites. "Activities that stand to disrupt the surface integrity of Railroad Valley would risk making the site unusable," Jeremy Eggers, a spokesman for NASA's Goddard Space Flight Center in Greenbelt, Maryland, told The Associated Press.
One company with most of the mining rights says the tract's withdrawal will put more than half the site's value out of reach, according to the article.

But the Associated Press got a supportive quote for the move from the satellite imaging company Planet Labs, which has relied on NASA's site to calibrate more than 250 of its satellites since 2016. "As our nation becomes ever more impacted by an evolving and changing environment, it is critical to have reliable and accurate data and imagery of our planet."

The "BepiColombo" mission, a joint European-Japanese effort, "has recently completed its third of six planned flybys of Mercury, capturing dozens of images in the process," reports the Byte: At its closest, the spacecraft soared within just 150 miles of Mercury. This occurred on the night side of the planet, however, too dark for optimal imaging. Instead, the first and nearest image was taken 12 minutes after the closest approach, at the still impressive proximity of some 1,100 miles above the surface.
Now the ESA has spliced together 217 images from that flyby into a short video, which culminates with a zoomed-in closeup of Mercury's cratered surface. And the music in that video had a little help from AI, reports Phys.org: Music was composed for the sequence by ILÄ (formerly known as Anil Sebastian), with the assistance of AI tools developed by the Machine Intelligence for Musical Audio group, University of Sheffield.

Music from the previous two flyby movies — composed by Maison Mercury Jones' creative director ILÄ and Ingmar Kamalagharan — was given to the AI tool to suggest seeds for the new composition, which ILÄ then chose from to edit and weave together with other elements into the new piece.

The team at the University of Sheffield has developed an Artificial Musical Intelligence (AMI), a large-scale general-purpose deep neural network that can be personalized to individual musicians and use cases. The project with the University of Sheffield is aimed at exploring the boundaries of the ethics of AI creativity, while also emphasizing the essential contributions of the (human) composer.
From the ESA's announcement: BepiColombo's next Mercury flyby will take place on 5 September 2024, but there is plenty of work to occupy the teams in the meantime... BepiColombo's Mercury Transfer Module will complete over 15 000 hours of solar electric propulsion operations over its lifetime, which together with nine planetary flybys in total — one at Earth, two at Venus, and six at Mercury — will guide the spacecraft towards Mercury orbit.

The ESA-led Mercury Planetary Orbiter and the JAXA-led Mercury Magnetospheric Orbiter modules will separate into complementary orbits around the planet, and their main science mission will begin in early 2026.
One spaceflight blog notes the propulsive energy required for an eventual entry into the orbit of Mercury "is greater than that of a mission to fly by Pluto.

"Only one other spacecraft has orbited Mercury, and that was NASA's MESSENGER probe, which orbited the planet from 2011 to 2015."

Finland's University of Jyväskylä has an announcement: an experiment performed in its accelerator lab "has succeeded in producing a previously unknown atomic nucleus."

Dubbed "190-Astatine," it's made from 85 protons and 105 neutrons.. The nucleus is the lightest isotope of astatine discovered to date. Astatine is a fast-decaying, and therefore rare element. It has been estimated that in the Earth's crust, there is no more than one tablespoon of astatine...

The new isotope was produced in the fusion of 84Sr beam particles and silver target atoms. The isotope was detected among the products by using the detectors of RITU recoil separator... "The studies of new nuclei are important for understanding the structure of atomic nuclei and the limits of known matter," says Doctoral Researcher Henna Kokkonen from the Department of Physics, University of Jyväskylä.

Motherboard reports: Scientists are currently searching for the submerged remains of an interstellar object that crashed into the skies near Papua New Guinea in January 2014 and probably sprinkled material from another star system into the Pacific Ocean, according to an onboard diary by Avi Loeb, the Harvard astronomer who is leading the expedition. The effort, which kicked off on June 14, aims to recover what is left of the otherworldly fireball using a deep-sea magnetic sled.

The team has already turned up "anomalous" magnetic spherules, steel shards, curious wires, and heaps of volcanic ash, but has not identified anything that is unambiguously extraterrestrial — or interstellar — at this point. However, Loeb is optimistic that the crew will identify pieces of Interstellar Meteor 1 (IM1), the mysterious half-ton object that struck Earth nearly a decade ago, which he thinks could be an artifact, or "technosignature," from an alien civilization...

The fireball that sparked the hunt smashed into the atmosphere on January 8, 2014, and was detected by NASA's Center for Near-Earth Object Studies (CNEOS), which keeps track of extraterrestrial impacts using a network of sensors around the world. Years later, Loeb and his student, Amir Siraj, concluded that the meteor's high velocity at impact suggested that it was interstellar in origin, a hypothesis that was ultimately supported by the United States Space Command using classified sensor data.
Today Loeb posted on Medium that "by now, we have 25 spherules from the site of the first recognized interstellar meteor," with a cumulative weight of about 30 milligrams — estimated to be one part in ten million of the original fireball's mass: The success of the Interstellar Expedition constitutes the first opportunity for astronomers to learn about interstellar space by using a microscope rather than a telescope. It opens the door for a new branch of observational astronomy.
Updates about the expedition are running on the Mega Screen in New York's Times Square, Motherboard reports. And Loeb writes that "If further analysis of the 50 milligrams retrieved from IM1's site will inform us that IM1's composition requires a technological origin, we will know that we are not alone."

He also shared an email that responded to his online diaries: I had a heart attack four weeks ago and am now in rehab. I read your IM1 diary every day and it always gives me new courage to face life. There are still so many things to discover and I want to live long enough to see some of them. I wish you and your team all the best.

The EPA is assembling its first-ever National Environmental Youth Advisory Council, a group of young people to weigh in on issues that affect their communities. From a report: "We can't tackle the environmental challenges of our time without input from our younger communities, who've long been at the forefront of social movements," EPA Administrator Michael Regan said in a press release yesterday. The worst effects of climate change are still ahead as greenhouse gas emissions from fossil fuels keep building up in Earth's atmosphere. The actions policymakers take today to curb that pollution will decide what kind of planet younger generations will inherit. So it makes sense for the EPA to create seats for them at the table.

According to AST SpaceMobile, the company managed to successfully transmit a 4G LTE signal from space that was picked up by "everyday, off-the-shelf smartphones." Next, AST will try and transmit a 5G connection via its BlueWalker 3 (BW3) satellite. The Verge reports: Testing was conducted in Hawaii on AT&T's spectrum using Nokia RAN technology, and the signal, which was beamed from AST's satellite in low Earth orbit, reached speeds of up to 10.3Mbps. That's fast enough for some video streaming, general internet use, and more ordinary cell phone usage. AST's testing followed a recent April test by the same company, where it was able to route an audio call between a Samsung Galaxy S22 in Texas to an iPhone in Japan via satellite.

The BW3 is a massive commercial communication array at 693 square feet -- about the size of a two- or three-car garage -- and the largest ever deployed in low Earth orbit, says AST's release. It operates using the same 3GPP standard found in ground-based cell networks. The achievement is "an important step toward AST SpaceMobile's goal of bringing broadband services to parts of the world where cellular coverage is either unreliable or simply does not exist today," according to AST's chairman and CEO, Abel Avellan, who said this would allow users to text and call, browse the internet, download files, and even stream video using a signal beamed from space.

An anonymous reader shares a report: The world of Secret Invasion is decidedly sketchy. With thousands of shapeshifting Skrulls on Earth, you can't trust what you think you're seeing. One second, you're looking at Nick Fury or an esteemed world leader; the next, you see their face morph into something (or someone) else entirely. This is a description of the plot of the new Marvel Cinematic Universe show on Disney Plus (as well as its comic book counterpart), which follows Nick Fury as he uncovers -- what else? -- a secret invasion by the Skrull population on Earth. But the concept of shape-shifting is also seen in the series' very different approach to its opening credits, which look like a sort of watercolor rendering of the key players and themes of Secret Invasion.

As we see a sort of jittery and ominous sequence of the Skrull green taking over more and more of the world, it looks a lot like if an AI was prompted with the concept of "Skrull cubism" -- which, actually, isn't that far off of what it is. As director and executive producer Ali Selim tells Polygon, the intro sequence was designed by Method Studios using artificial intelligence, something he thinks plays with the very themes of the show. "When we reached out to the AI vendors, that was part of it -- it just came right out of the shape-shifting, Skrull world identity, you know? Who did this? Who is this?" Selim says. Like many people, Selim says he doesn't "really understand" how the artificial intelligence works, but was fascinated with the ways in which the AI could translate the sense of foreboding he wanted for the series. "We would talk to them about ideas and themes and words, and then the computer would go off and do something. And then we could change it a little bit by using words, and it would change."
