  Rubin Observatory Discovers Over 11,000 Asteroids Within Weeks of Imaging

  The Vera Rubin Observatory has discovered over 11,000 new asteroids within weeks of early observations. The findings highlight its ability to rapidly map the solar system and improve tracking of near-Earth objects for planetary defence.

  Hubble Telescope Captures Comet Reversing Its Rotation for the First Time

  Using the Hubble Space Telescope, astronomers observed Comet 41P slow, stop, and reverse its spin due to gas jets. The rare phenomenon could mark the beginning of the comet’s breakup as it nears the end of its life.

  Brown Dwarf Merger Could Create a New Star, Astronomers Discover

  Astronomers have discovered a rare brown dwarf binary system undergoing mass transfer with an ultra-short orbit. The pair could either merge or gain enough mass to ignite fusion, potentially forming a new star and redefining how “failed stars” evolve.

  Ancient Star in Pictor II Reveals Secrets of Early Universe

  Astronomers have discovered one of the oldest known stars, PicII-503, in the Pictor II dwarf galaxy. With extremely low iron content, the star offers rare insight into the second generation of stars and the early chemical evolution of the universe.

  Chandra Detects Giant X-Ray Bubble Around Young Sun-Like Star HD 61005

  NASA astronomers using the Chandra X-ray Observatory have discovered a vast, million-degree gas bubble surrounding HD 61005, a 100-million-year-old Sun-like star about 120 light-years away. Its stellar wind is far stronger than today’s solar wind, forming a 200 astronomical unit-wide astrosphere that offers rare insight into how the young Sun onc...

  Scientists Identify Rare Black Hole Merger in the Early Universe Using Gravitational Mapping

  Astronomers have identified two merging supermassive black hole systems named Gondor and Rohan using a new method combining quasars and gravitational wave background signals. The discovery offers a fresh way to map black hole mergers and understand galaxy evolution and cosmic gravitational waves in a clearer and more systematic manner.

  Unique Inside-Out Planetary System Reveals Unexpected Rocky World on the Outer Edge

  Astronomers have discovered a rare inside-out planetary system around LHS 1903, where a rocky planet exists beyond gas giants. Using ESA’s CHEOPS telescope, researchers found evidence that planets formed one after another in a gas-depleted environment, challenging long-standing theories about how planetary systems form and evolve across the galax...
