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

ESA's XMM-Newton telescope has become instrumental in monitoring an extraordinary cosmic awakening: a massive black hole in a galaxy 300 million light-years away has transitioned from complete dormancy to producing the most powerful and extended X-ray eruptions ever observed. The black hole lies in SDSS1335+0728, an otherwise unremarkable galaxy in Virgo. After decades of inactivity, it be

Earth planning date: Wednesday, April 9, 2025: Our drive from Monday's plan was mostly successful, putting us ~22 meters down the "road" out of an expected 30 meters. A steering command halted the drive a little short when we tried to turn-in-place but instead turned into a rock, which also had the effect of making our position too unstable for arm activities. Oh well! APXS data has been showing

Astronomers at W. M. Keck Observatory on Maunakea, Hawai'i, have traced the origin of 2024 YR4, an Earth-crossing asteroid discovered in December 2024, to a surprising location. Contrary to expectations, the solid, stony asteroid appears to have emerged from a central Main Belt asteroid family between Mars and Jupiter-a region not previously associated with Earth-crossing bodies. "YR4 spin

Washington DC (SPX) Apr 14, 2025
The asteroid 2024 YR4 made headlines in February with the news that it had a chance of hitting Earth on Dec. 22, 2032, as determined by an analysis from NASA's Center for Near Earth Object Studies (CNEOS) at the agency's Jet Propulsion Laboratory in Southern California. The probability of collision peaked at over 3% on Feb. 18 - the highest ever recorded for an object of its size. This sparked c
