New research attributes the rare, prolonged eclipse of ASASSN-24fw to a massive ring system around a brown dwarf or super-Jupiter, offering insights into circumplanetary dynamics.
Read More 2026-02-16 A Distant Black Hole Keeps Getting Brighter and Stranger AT2018hyz, a tidal disruption event, has shown years-long radio brightening. New observations reveal dramatic energy growth, possible delayed outflow or off-axis jet, and implications for black hole physics.
Read More 2026-02-15 Could the Milky Way’s Heart Be Dense Dark Matter, Instead? An international team suggests the Milky Way’s central mass might be a dense fermionic dark matter core that imitates a black hole’s gravity, matching both S-star orbits and Gaia’s rotation curve while offering testable differences.
Read More 2026-02-14 A Lost Moon Crash May Explain Saturn’s Young Rings New simulations suggest Saturn's rings and Titan's odd orbit may stem from a collision between a proto-Titan and a smaller moon about 100 million years ago. Dragonfly could test the theory in the 2030s.
Read More 2026-02-14 How a Giant Star Vanished Quietly and Became a Black Hole A supergiant in Andromeda quietly collapsed into a black hole after a failed supernova. Archival NEOWISE and optical data show an infrared brightening then a tenfold fade, reshaping how massive stars die.
Read More 2026-02-13 Why Mars' Long-Chain Organics Defy Abiotic Explanations A NASA-led study argues that alkanes detected by Curiosity may have originally been far more abundant than measured, and that known abiotic sources struggle to explain those inferred concentrations on ancient Mars.

Read More 2026-02-11 Could Dark Matter Replace the Milky Way's Black Hole? New research suggests the Milky Way's central mass—traditionally identified as the black hole Sagittarius A*—could instead be a compact fermionic dark matter core. Current stellar or imaging data cannot yet distinguish between the two.

Read More 2026-02-09 Musk's Pivot: SpaceX Aims to Build a City on the Moon Elon Musk has announced SpaceX will prioritize building a self-sustaining city on the Moon, citing frequent travel windows and faster logistics than Mars. The shift reframes near-term goals while keeping Mars aspirations alive.
Read More 2026-02-08 Runaway Black Holes Aren't Myth: Cosmic Fugitives Now Astronomers increasingly accept that 'runaway' black holes exist: mergers can kick resulting black holes at thousands of km/s, leaving stellar contrails that recent JWST and galaxy observations appear to reveal.
Read More 2026-02-08 When Earth's Magnetic Poles Took Tens of Thousands of Years New analysis of Eocene seafloor cores shows some geomagnetic reversals unfolded over tens of thousands of years, reshaping how scientists view the geodynamo, atmospheric effects, and biological impacts.
Read More 2026-02-07 An Ice-Cold Earth Candidate Found 150 Light-Years Away Scientists have identified HD 137010 b, an Earth-sized exoplanet candidate about 150 light-years away. It orbits a long-lived K dwarf in roughly one year and may be a frozen ‘snowball’ or, with the right atmosphere, retain liquid water.
