Euclid has uncovered an unexpected gap in NGC 6397, a globular cluster about 8,000 light-years from Earth. The missing patch appears among faint red dwarfs, where astronomers would normally expect a denser spread of stars. The most likely explanation is a short transition stage in red dwarf evolution, when their interiors shift from partly convective to fully convective. Because that phase is brief, relatively few stars are seen there. The finding gives astronomers a new way to test stellar evolution models and may also help improve distance measurements.

Using Gaia data, astronomers have found 87 candidate stellar streams in the Milky Way’s outskirts. These streams are likely the stretched remains of ancient star clusters shaped by the galaxy’s gravity over immense spans of time. Many of the newly identified streams are not the tidy structures researchers expected. Some are shorter, wider, or misaligned, hinting that older search techniques missed a large hidden population. That matters because stellar streams act like gravitational records. They can help scientists reconstruct how the Milky Way formed and refine our picture of its dark matter halo.

A rare interstellar visitor just got even more interesting. Webb observations of 3I/ATLAS revealed methane, the first direct detection of methane in any interstellar object. Scientists say the methane likely stayed hidden beneath the comet’s surface until heating after its close solar pass released it. With carbon dioxide also unusually abundant, 3I/ATLAS appears chemically unlike most comets from our own Solar System. Only three interstellar objects have ever been confirmed, so every new measurement matters. #jameswebb #jwst #3iatlas #interstellarobject #interstellarcomet #spacenews #astronomy #methane #comet #nasa #esa #science

Venera 7 looked lost after a brutal landing on Venus, but the mission was not over. Despite a partial parachute failure and a hard impact, the probe kept transmitting for 23 minutes from the surface. That faint signal became humanity’s first direct data from another planet’s surface, confirming Venus as an extreme world and proving future landers could survive long enough to explore it.

The Nancy Grace Roman Space Telescope could reshape exoplanet research by surveying the crowded center of the Milky Way. Instead of focusing mostly on nearby stars, Roman will watch hundreds of millions of stars and is expected to find around 100,000 close-in giant planets through transits. Gravitational microlensing could add more than 1,000 distant planets, including worlds as small as Earth or even Mars that are usually very difficult to detect. The mission may also provide infrared data on thousands of giant exoplanet atmospheres, helping scientists study temperatures and possible wind patterns. Together, these discoveries could offer a powerful new way to test how planets form across our galaxy and how common systems like ours may be.

A faint halo around Venus changed astronomy. During the 1761 transit of Venus, Mikhail Lomonosov spotted a thin arc of light and realized it could be explained by sunlight passing through gas around the planet. His conclusion was extraordinary: Venus has an atmosphere. It was the first confirmed discovery of an atmosphere beyond Earth and a milestone in the study of other worlds.

The James Webb Space Telescope has helped astronomers identify the most distant dormant supermassive black hole known so far. Located about 10 billion light-years away in galaxy MRG-M0138, it has a mass of roughly 6 billion Suns. The surprise is that it is not actively feeding, so it is not producing the brilliant glow usually linked to quasars. Researchers could study it because gravitational lensing from a foreground galaxy magnified the light from the distant system. The data suggest this black hole may once have been a powerful quasar that grew quickly, drove away much of the surrounding gas, and eventually ran out of nearby fuel. That makes it an important clue to how supermassive black holes formed and influenced galaxy growth in the young Universe.

The Arietids peak around June 10 and rank among the strongest meteor showers of the year, but most of them flash through daylight near the Sun. To catch a visible few, look low toward the eastern horizon about 45 to 60 minutes before sunrise. They can appear to rise from the horizon or glide low across the sky. Even more unusual, their ionized trails may briefly reflect distant FM broadcasts. On an unused FM frequency, that can sound like sudden voices or music appearing out of static. No optics needed. Avoid binoculars and telescopes near sunrise because of the danger of accidentally viewing the Sun. This is a rare chance to combine skywatching with a simple radio experiment. #arietids #meteorshower #astronomy #radioastronomy #skywatching #space #sunrisesky #fmradio

AstroForge has completed assembly of DeepSpace-2, a low-cost spacecraft built to fly past a near-Earth asteroid later this year. The mission follows the loss of Odin, which failed shortly after launch when its solar panels did not deploy as expected. For DeepSpace-2, engineers redesigned the power system so the spacecraft can keep working even if a panel only partially unfolds, and they added stronger backup modes. The point of the mission is to validate an affordable interplanetary platform rather than deliver a major science campaign. DeepSpace-2 carries two high-resolution cameras and costs under $10.5 million in total. Depending on the launch date, it will target one of several candidate asteroids and arrive after 2 to 9 months. If successful, the mission could strengthen the case for practical low-cost asteroid scouting and future commercial deep-space missions.

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.
