Read More 2026-01-08 Dead Star Awakens: IXPE Reveals White Dwarf Drama Now IXPE used X-ray polarimetry to map EX Hydrae's accretion column around a white dwarf, estimating a ~2,000-mile column height and revealing how magnetism and gravity shape high-energy emission.
Read More 2026-01-07 Impossibly Hot Cluster Found 1.4 Gyr After Big Bang ALMA observations of galaxy cluster SPT2349-56, seen 1.4 billion years after the Big Bang, reveal intracluster gas far hotter than models predict — pointing to early, powerful black-hole feedback.
Read More 2026-01-07 Researchers Tracked a Superactive Solar Region 94 Days By combining Solar Orbiter and SDO data, scientists tracked superactive region NOAA 13664 for 94 days, mapping its magnetic evolution and linking complexity to major geomagnetic storms that affected Earth.
Read More 2026-01-07 Quiet Depths: Could Europa’s Ocean Be Lifeless Today? New research argues Europa's subsurface ocean may lack the seafloor activity needed to power life. Models suggest weak tidal heating and a cooled interior could leave the seafloor geologically quiet today.
Read More 2026-01-05 Earth's Magnetic Field Funnels Atmosphere to the Moon New research shows Earth's magnetic field can guide charged atmospheric particles along field lines to the Moon. Lunar soil may record Earth's atmospheric history and offer usable volatiles for future explorers.
Read More 2026-01-04 Black Hole Twists Spacetime: Evidence for Frame-Dragging Astronomers observed a tidal disruption event (AT2020afhd) where a spinning black hole twisted spacetime, producing a 20-day wobble in both the accretion disk and relativistic jet — direct evidence of frame-dragging.
Read More 2026-01-04 January's Rare Wolf Supermoon: A Triple Brightness Boost The Wolf Supermoon on 3 January 2026 will be brighter and slightly larger than usual due to lunar perigee, Earth's perihelion, and clearer winter skies—making this a rare triple-boost lunar event.
Read More 2026-01-03 Webb Finds Thick Atmosphere on Scorching Super-Earth JWST NIRSpec observations indicate the ultra-hot super-Earth TOI-561 b retains a thick, volatile-rich atmosphere above a global magma ocean, challenging models of atmospheric loss on small, irradiated planets.
