Astronomers have now pinned down one of the universe’s most extreme thresholds: the maximum mass of a non-rotating neutron star is about 2.25 times the mass of the Sun, with only 2% uncertainty. Using NICER observations, LIGO gravitational-wave data, and theoretical models of ultra-dense matter, researchers identified the point beyond which a neutron star can no longer support itself against gravity and must collapse into a black hole. This sharper limit strengthens the case that the 2.59-solar-mass object in GW190814 is a lightweight black hole, not a neutron star. It also confirms that a typical neutron star is only about 12 kilometers across.

A neutron star heavier than ~2.25 Suns likely can’t exist without collapsing. That makes GW190814’s 2.59-solar-mass object look much more like a black hole. Made by shorts.wixee.ai

A prototype antenna for the next-generation Very Large Array has successfully achieved first light in New Mexico. The dish observed the Sun, the Crab Nebula, and active galactic nuclei, then joined the existing VLA as a temporary 28th antenna to observe Perseus A. This is a major milestone toward the full ngVLA, a planned radio observatory of 244 antennas spread across more than 8,000 kilometers of North America. The array is expected to deliver about 10 times the sensitivity and resolution of current leading radio observatories, helping scientists explore galaxy formation, black holes, star birth, and the structure of the Universe.

The James Webb Space Telescope detected a clear methane signature in the atmosphere of TOI-199b, a temperate Saturn-like exoplanet around 335 light-years away. Webb made the detection by studying starlight passing through the planet’s atmosphere during transit. The result confirms a major prediction: cooler gas giants should show methane in their atmospheres more clearly than the hotter giants often observed. Scientists also found tentative hints of carbon dioxide and ammonia, but those signals still need confirmation. TOI-199b now stands out as a key benchmark for understanding how giant planets form, evolve, and compare with the worlds in our own Solar System.

A seat on a Russian spaceflight could cost around 2 billion rubles, roughly $25 million, based on total launch expenses split across participants. There is an important detail: every mission would still require at least two professional crew members for safety and emergency response, so not all seats would be open to tourists. Roscosmos describes this as a premium category because launch systems and spacecraft operations are still costly. It also extends the idea of space tourism beyond flying, including factory visits, launch facility access, and engine test site tours. That pricing is similar to past orbital tourism missions. For now, access remains limited to very wealthy individuals, though costs could decline over time if reusable spacecraft and more frequent launches become standard.

Alexei Leonov’s 1965 spacewalk was a milestone in human history—and a terrifying survival story. After leaving Voskhod 2, he found that the vacuum had inflated and stiffened his suit so badly that he struggled to re-enter the airlock. He made it back only after lowering suit pressure and forcing himself through. Then the mission suffered more problems, including re-entry trouble and a remote landing in a frozen Siberian forest. Leonov and Pavel Belyayev spent two nights waiting for rescue. This mission opened the era of EVA while showing just how dangerous it would be.

New observations of Cepheus A HW2 suggest cosmic radiation may do more than break molecules apart. In the most strongly irradiated region around this massive young star, astronomers detected abundant complex organic molecules, including methanol, methyl cyanide, acetaldehyde, ketene, and methyl formate. The likely process is that cosmic rays disrupt simple ices on dust grains, trigger new chemical reactions, and help release freshly formed organics into space. Even more surprising, this irradiated zone showed much richer chemistry than a nearby control region with ordinary radiation levels. The discovery points to a bigger possibility: violent stellar nurseries may be active sites of prebiotic chemistry, broadening where the building blocks of life could arise in the Universe.

NASA is considering whether the Hubble Space Telescope could be lifted into a higher orbit to delay reentry beyond 2033. The concept is tied to a commercial rendezvous-and-boost mission planned for the Neil Gehrels Swift Observatory. If that mission succeeds and NASA finds a way to lower Hubble’s operating costs, the observatory could remain scientifically active into the 2040s, helping bridge the gap before future flagship missions arrive.

Astronomers have directly tracked the rotation of the planet-forming disk around AB Aurigae and uncovered clear signs of active planet formation. Observations with SPHERE on the Very Large Telescope show gas and dust moving in patterns that simple gravity does not fully account for, likely because massive protoplanets are already disturbing the disk. Together with AB Aurigae b and the system’s spiral arms, shadows, and twisted features, the data offer one of the strongest real-time views yet of a young solar system emerging from gas and dust.

A new study proposes that vast numbers of unseen interstellar comets and asteroids may contribute part of the Milky Way’s apparent missing mass. Starting from known interstellar visitors such as 1I/‘Oumuamua, 2I/Borisov, and 3I/ATLAS, researchers used statistical models to estimate how much mass a hidden Galactic population of similar objects could add. Their result suggests these wanderers might explain about 13% to 45% of the discrepancy inferred from the Milky Way’s rotation curve. Important caution: this hypothesis is based on very limited observational evidence and broad extrapolation from only a few detections. Even if supported, it would not remove the need for dark matter, though it could reduce the amount required and affect how some detection results are interpreted. Future sky surveys should provide the data needed to test whether these hidden interstellar bodies meaningfully contribute to the Galaxy’s mass budget. Follow for the next sky survey result that could prove this idea right or wrong. #s

A new study examined whether NASA’s planned Habitable Worlds Observatory could have detected life on Earth from light-years away at different stages of our planet’s history. By modeling eras from the Archean Earth—when oxygen was scarce and life was mostly microbial—to the modern oxygen-rich world, researchers found that the telescope should be able to identify major biosignatures such as oxygen, ozone, water vapor, methane, and carbon dioxide if it reaches the needed spectral resolution. The work also sets concrete design goals. Relatively modest ultraviolet and visible-light performance may be enough for ozone and oxygen detection, while stronger infrared resolution is more important for telling possible biological signals apart from geological ones. The bigger implication is extraordinary: a future observatory like this might provide humanity’s first strong evidence that life exists on another world.
