New research from the Leibniz Institute for Astrophysics Potsdam (AIP) has revealed a striking anomaly in the satellite galaxy system surrounding Andromeda (M31), casting doubt on long-held assumptions within standard cosmology. The study, published in Nature Astronomy, shows that more than 80% of Andromeda's dwarf galaxy companions are clustered on one side of the host galaxy-a configuration pr

Rough terrain, deep shadows and blinding light – training for lunar missions means facing an environment unlike anything on Earth. At the ESA-DLR LUNA analogue facility, virtual reality (VR) technology makes it possible for astronauts to immerse themselves in a 360-degree simulation of the lunar surface without leaving the ground.

The Expedition 72 team aboard the International Space Station (ISS) closed out their week with a focus on spacesuit enhancements and critical biomedical research. As one group adjusted to the rigors of microgravity, another prepared for their journey home after months in orbit. NASA astronauts Anne McClain and Nichole Ayers spent Friday outfitting two spacesuits with newly installed displa

A new analysis from Novaspace, a prominent space sector consultancy, warns that the rapidly expanding satellite population is pushing orbital collision risk toward a critical tipping point. To confront this growing challenge, the firm has launched its inaugural Space Situational and Domain Awareness (SSDA) Market Intelligence Report. "With the increasing deployment of mega-constellations i

A massive black hole at the heart of a galaxy in the Virgo constellation is waking up, shooting out intense X-ray flares at regular intervals that have puzzled scientists, a study said Friday. Astronomers previously had little reason to pay any attention to galaxy SDSS1335+0728, which is 300 million light years from Earth. But in 2019, the galaxy suddenly started shining with a brightnes

Every galaxy is thought to form at the center of a dark matter halo - a region of gravitationally bound matter that extends far beyond the visible boundaries of a galaxy. Stars are formed when gravity within dark matter halos draws in gas, but astrophysicists don't yet know whether star-free dark matter halos exist. Now Ethan Nadler, a computational astrophysicist at UC San Diego, has calc

New research led by Satoya Nakano and Kengo Tachihara at Nagoya University has uncovered compelling evidence that the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors, is undergoing tidal disruption due to gravitational forces from its larger companion, the Large Magellanic Cloud (LMC). Published in The Astrophysical Journal Supplement Series, the findings offer ne

The Solar Orbiter mission, a collaboration between NASA and ESA, has detected the most intense concentration of the rare helium-3 (3He) isotope ever recorded from the Sun, sparking new interest in the origin of solar energetic particles (SEPs). Scientists led by Southwest Research Institute (SwRI) have now traced the source of this extraordinary event to a diminutive solar jet on the Sun's surfa
