Longtime Slashdot reader schwit1 shares a report from Behind the Black: In a new bid to get the Thirty Meter Telescope (TMT) to move from Hawaii, which has blocked its construction for more than a decade, the Spanish government has put together a $1.14 billion package that would not only pay for construction on the Canary Islands, but would finance an additional half century of operations. Tech Times provides some additional details: The package is conditional on the TMT International Observatory formally choosing La Palma as its construction site. The financing architecture has three pillars and two additional contingent instruments. The first pillar is 400 million euros (approximately $456 million USD) from Spain's Ministry of Science, Innovation and Universities, routed through the Centre for Technological Development and Innovation (CDTI). This figure was first pledged a year ago in July 2025 as Spain's initial bid. The second pillar is a 300 million-euro (approximately $342 million USD) loan from the EIB [European Investment Bank] itself -- subject to satisfactory completion of the bank's technical, financial, and legal due diligence and approval by its governing bodies. The third is a potential 300 million-euro (approximately $342 million USD) participation from the Instituto de Credito Oficial (ICO), Spain's state development finance institution, evaluated under equivalent conditions to the EIB loan but subject to its own separate analysis. Spain's export credit agency, Cesce, may also provide coverage instruments, and the EIB has left open the possibility of expanding its support through intermediated financing mechanisms or guarantees.

"Scientists say they have detected promising signs that a planet orbiting a star 49 light-years from Earth could have an atmosphere," reports CNN, "making it potentially suitable for life." Called LHS 1140b, the object is about five times the mass of our planet, or a "super-Earth." This planet orbits around its star in the "Goldilocks zone," also known as the habitable zone, meaning its surface temperature is not too hot or too cold for liquid water to exist... "It appears to be consistent with Earth, meaning it might have an iron core and a silicate mantle, plus some sort of low-density component, which is probably a combination of water and, now we know, an atmosphere," [said Collin Cherubim, a planetary scientist and lead author of a paper on the finding, published July 16 in the journal Science]... If further observations confirm the findings, LHS 1140b would mark the first discovery of an atmosphere on a rocky planet in the habitable zone of another star... There is no evidence of life or a life-supporting atmosphere on LHS 1140b now, but Cherubim said he believes it's a formidable candidate for potential signatures of extraterrestrial life. "I think it's the best place to look for life outside the solar system at this point," he said. "It's mostly rocky, it's at the right temperature to support liquid water on the surface, and it has an atmosphere — those are the three key ingredients we look for..." Confirming the existence of an atmosphere on a rocky planet orbiting a red dwarf would be particularly exciting, Cherubim said, because the possibility of that happening is an open question in astronomy. "Can rocky planets have atmospheres around red dwarfs? This is the first bona fide yes," he said. "It's kind of a sigh of relief for a lot of us. But the jury's still out. Maybe this is a weird planet, and it's an oddball, or maybe it's the first of many. We don't know yet." Now "The James Webb Space Telescope is going to look at it," Cherubim told CNN, and "Hubble's going to look at it. Basically, everybody who can see it is going to be training their eyes on it." Michaël Gillon, research director of the Astrobiology Research Unit at Belgium's University of Liège warned CNN that no definitive proof exists that LHS 1140b possesses a substantial atmosphere. But if the detection of helium can be confirmed, the implications would be profound. "Until now, we had only limited evidence for atmospheres on temperate rocky exoplanets. Demonstrating that LHS 1140 b has retained a substantial atmosphere over billions of years would show that at least some habitable zone Super-Earths around red dwarfs can survive the intense early activity of their host stars."

SpaceX's Friday launch of its massive Starship rocket "went quite smoothly," reports CNN, with a SpaceX spokesperson calling this mission "Lucky Number 13" (as the 13th integrated flight test for a Starship spacecraft with a Super Heavy rocket booster): During Starship V3's inaugural test, there were numerous engine issues as several on the booster failed to relight and the Starship spacecraft experienced a nail-biting engine outage. SpaceX also was forced to replace six engines on this vehicle ahead of today's flight because of a likely issue with moisture that prevented at least four from starting up correctly during an initial launch attempt last week... [Friday's Super Heavy rocket booster] fired all 33 of its engines in a pristine performance off the launchpad. The rocket booster also managed to relight 13 engines, as planned, to steer itself back toward a controlled landing. Only when Super Heavy attempted to relight its engines for a controlled landing burn over the Gulf waters did problems arise. The landing was still controlled, though Huot said the vehicle was traveling a bit faster than the company had hoped when it made touchdown. (SpaceX always intended to discard this Super Heavy booster in the ocean.) The Starship spacecraft had no obvious performance issues, making it all the way through its engine burn and managing to reignite one engine mid-flight as part of a test. It also made a controlled splashdown in the Indian Ocean — executing its "softest splashdown" to date in a "dream scenario," according to SpaceX's Dan Huot. The touchdown came about an hour after takeoff, as planned. During its coasting phase, Starship also deployed 20 Starlink test satellites, paving the way for operational missions later down the line in which SpaceX plans to deploy large batches of these satellites in a single launch. In another big win, SpaceX said it was able to make contact with each of those satellites. CNN adds that SpaceX "is facing intense pressure to get Starship ready for a crucial NASA test flight next year that could pave the way for the next moon landing. This flight was also the first for SpaceX as a publicly traded company. Last week's aborted launch attempt sparked a selloff, and shares are still trading below their IPO price. "To cap off the roaring success of today's flight test, SpaceX shared some stunning visuals of the upper Starship spacecraft sailing through space."

Astronomers studying the star system CD-35 2722 may have found the first known moon-like object outside our solar system. The classification is unusually tricky, however, because it orbits a brown dwarf rather than a planet, making it clearly an "exosatellite" but forcing scientists to rethink where the line between planet, moon, and failed star should be drawn. Space.com reports: The star CD-35 2722 is located around 73 light-years away and has around half the mass of the sun. It is orbited by a "failed star" or brown dwarf. These stellar bodies get their unfortunate nickname because they form like other stars but fail to gather enough mass to trigger the fusion of hydrogen to helium in their cores. In terms of mass, brown dwarfs are more massive than the largest gas giant planets, but smaller than the smallest stars, usually with around 13 to 80 times the mass of Jupiter, or around 0.013 to 0.08 times the mass of the sun. The newly discovered object in CD-35 2722 is certainly moon-like, but rather than orbiting a planet as the moons in the solar system do, it orbits the system's brown dwarf. "This system is somewhat hard to define using solar-system-based words like 'planet' and 'moon.' The exosatellite is clearly massive enough to be a planet, but it does not orbit a star, though it orbits an object that orbits a star," team leader Kevin Hoy of the Universidad Diego Portales and the Millennium Nucleus of Young Exoplanets and their Moons (YEMS) in Chile, said in a statement. "Being the third wheel in this system makes us want to call it a moon, even if it is nothing like the small, rocky moons we have in our system." The team currently isn't able to definitively claim this object in CD-35 2722 is an exomoon, because that would require really nailing down a new definition of what a moon is. "The satellite we report is a giant gaseous body orbiting a highly massive companion, itself several times the mass of Jupiter. We have a clear delineation between the planets and the sun in the solar system, so defining things like moons is simple," team member Alice Zurlo of the Universidad Diego Portales said. "In the CD-35 2722 system, where we are blurring the lines between stars, planets, and moons, the whole thing becomes more complicated to describe." Zurlo and colleagues can, however, confidently claim this is an exosatellite, meaning it is a first-of-its-kind detection no matter what the future holds for its classification. The findings have been published in the journal Nature.

"Thanks to the James Webb Space Telescope, astronomers have been given a glimpse of the mechanisms that supermassive black holes use to feed themselves," reports Space.com: The powerful cosmic titans get really puzzling when astronomers using the JWST spot them before the universe was even 1 billion years old. That's because the mechanisms by which black holes devour matter to grow and then merge to create even more massive black holes should take at least 1 billion years to achieve supermassive status. This is even more confusing because theories also say the most ravenously feeding black holes (and thus the fastest growing) should also push the matter they use for this growth away, in effect putting themselves on a diet. So, with all this in mind, how did supermassive black holes grow so rapidly in the early universe? One explanation suggests supermassive black holes push away gas, starving themselves as predicted, but also that this matter eventually cools and falls back to the black hole. That would allow for another period of feeding and thus growth. This explanation further suggests that as this gas cools down, it forms "streamers," or filaments, of gas just a few hundred light-years wide but which stretch thousands of light-years long. These would fall back to the center of the galaxy and form a swirling disk around its incumbent black hole, once again feeding it and triggering a new period of growth. This would then restart the jets from the black hole, which would again cut off the cosmic titan's food supply, allowing the whole process to begin once more. The process would in essence be a self-regulating cycle of feasting followed by fasting. However, the connection between these filaments and supermassive black holes has been elusive, meaning this mechanism has resisted confirmation. To solve the mystery of feasting black holes, the JWST turned its attention to a relatively close AGN situated at the heart of the central galaxy of the Centaurus Cluster, NGC 4696, located just 145 million light-years from Earth. The Hubble Space Telescope previously studied this galaxy, uncovering a strange, hook-shaped swirl of gas near the central supermassive black hole of NGC 4696. The JWST followed up this discovery by producing a detailed map of gas flowing at the heart of the galaxy. This revealed the hook-shaped feature is around 800 light-years wide and is composed of gas moving at incredible speeds of around 1.3 million miles per hour (600 kilometers per second). More excitingly, the swirl of gas appears to be connected to a vast filament of material falling in toward the central supermassive black hole. The team tested the JWST observations against a computer simulation, finding gas in the infalling filament scenario would indeed take a shape similar to that seen in NGC 4696. "JWST is now showing us the final link of this closed loop," team member Helen Russell of the School of Physics and Astronomy at the University of Nottingham in the U.K. said in the statement. "The vast filamentary network of gas flows ultimately funnels gas down to a disk that fuels the black hole." The team's research was published on Wednesday (July 16) in the Astrophysical Journal Letters. "We are finally seeing this self-sustaining cycle in action," team leader Julie Hlavacek-Larrondo of the Université de Montréal said in a statement.
