    The Hubble Space Telescope just marked its 33rd year in orbit around the Earth with a remarkable gift for us all — an awe-inspiring new...

  • Most massive touching stars ever found will eventually collide as black holes

    Updated: 2023-04-27 16:45:12
    A new study looked at a known binary star (two stars orbiting around a mutual center of gravity), analyzing starlight obtained from a range of ground- and space-based telescopes. The researchers found that the stars, located in a neighboring dwarf galaxy called the Small Magellanic Cloud, are in partial contact and swapping material with each other, with one star currently 'feeding' off the other. They orbit each other every three days and are the most massive touching stars (known as contact binaries) yet observed.

  • Casting a safety net: A reliable machine learning approach for analyzing coalescing black holes

    Updated: 2023-04-27 16:45:04
    An interdisciplinary team has developed an algorithm that immediately checks its own calculations of merging black holes' properties and corrects its result if necessary -- inexpensively and rapidly. The machine learning method provides very accurate information about the observed gravitational waves and will be ready for use when the global network of gravitational-wave detectors starts its next observing run in May.

  • Direct image of a black hole expelling a powerful jet

    Updated: 2023-04-27 02:05:30
    Astronomers have observed, in one image, the shadow of the black hole at the center of the galaxy Messier 87 (M87) and the powerful jet expelled from it. Thanks to this new image, astronomers can better understand how black holes can launch such energetic jets.

  • Astronomers solve the 60-year mystery of quasars -- the most powerful objects in the Universe

    Updated: 2023-04-26 01:53:42
    Scientists have unlocked one of the biggest mysteries of quasars -- the brightest, most powerful objects in the Universe -- by discovering that they are ignited by galaxies colliding.

  • Medium-sized black holes eat stars like messy toddlers

    Updated: 2023-04-26 01:53:36
    In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, intermediate-mass black holes likely devour wayward stars like a messy toddler -- taking a few bites and then flinging the remains across the galaxy.
