So the mystery signal may not be a magnetar after all—it could be a 'vampire star' binary. Would you want a part 2 on how astronomers detected it? Made by shorts.wixee.ai

Astronomers found something unexpected in fast-spinning millisecond pulsars: many may emit radio waves from far farther out than previously believed. After comparing nearly 200 pulsars with Fermi gamma-ray observations, researchers concluded that about one-third likely produce radio emission from the current sheet, not just near the magnetic poles. This could mean more pulsars are visible from Earth than expected, which matters because pulsars are some of the most precise cosmic clocks known. They help scientists investigate gravitational waves and test fundamental physics.

SN 2017egm looked too bright to explain with ordinary supernova physics alone. Now astronomers report gamma rays from the explosion, offering the clearest evidence yet that a newborn magnetar may be powering it. A magnetar is a freshly formed neutron star that is incredibly dense, rapidly spinning, and wrapped in an immense magnetic field. Using observations from the Fermi Gamma-ray Space Telescope, researchers found the detected gamma rays match models where the magnetar pours energy into the expanding debris. This can generate particles and gamma rays, with some of that energy helping fuel the visible glow. The explosion took place about 440 million light-years away in NGC 3191 and is the first clear detection of this kind. It could give astronomers a new tool for understanding how the most luminous supernovas work and how extreme compact objects are born.

A neutrino with roughly 220 PeV of energy—by far the most extreme of its kind yet detected—appeared without a clear flash of light to identify where it came from. New simulations suggest the answer may lie in distant blazars, where supermassive black holes power enormous jets of plasma. Rather than one dramatic explosion, the signal may reflect the combined background activity of many blazars across the cosmos. That makes neutrinos especially valuable: they can travel immense distances with very little interference, carrying information from places light alone may not fully reveal.

Neutrinos barely interact with matter, which is why they can carry information across the Universe almost untouched. Made by shorts.wixee.ai

Scientists may be closer to solving one of astrophysics’ biggest mysteries. New simulations indicate that some extreme cosmic rays, including famous record-setting events, may be ultraheavy atomic nuclei heavier than iron. Because these particles can lose energy more slowly during their journey through space, they are more likely to survive all the way to Earth at extraordinary energies. That points to some of the cosmos’ most violent environments as possible sources, including neutron star mergers, gamma-ray bursts, and the collapse of massive stars into black holes or highly magnetized neutron stars.

On June 3, 1965, Ed White became the first American to perform a spacewalk. During Gemini 4, he spent about 23 minutes outside the spacecraft, connected by a tether and using a handheld compressed-gas maneuvering device to control his movement. The success of this experiment helped shape future EVA techniques and astronaut mobility systems.

NWA 12774, a rare meteorite found in the Sahara, may be a surviving fragment of a large protoplanet from the Solar System’s earliest era. Scientists detected aluminum-rich minerals that seem to require far higher pressures than a small asteroid could generate. That clue suggests a much larger parent world—possibly Moon-sized or more. As an angrite, this meteorite is especially unusual and may preserve evidence of early planetary bodies that were later shattered, with remnants potentially incorporated into worlds like Earth.

Messier 88 is a beautiful spiral galaxy in the Virgo Cluster, about 63 million light-years away. Hubble’s latest image reveals tightly wound arms filled with young star clusters, dark dust clouds, and older reddish stars around a brilliant center powered by a supermassive black hole roughly 100 million times the mass of the Sun. But this is more than a beautiful portrait. Messier 88 is moving through the hot gas that fills the Virgo Cluster, and that environment is gradually stripping away the cold gas needed to form new stars. In the long term, this means the galaxy may become quieter and less active in star formation. In around 200 to 300 million years, Messier 88 will pass near the giant elliptical galaxy Messier 87 as it continues falling toward the cluster’s crowded center. It is a powerful example of how galaxy clusters can reshape and age the galaxies within them.

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
