  • A lot of galaxies need guarding
    on May 4, 2017 at 2:18 pm

    Like the quirky characters in the upcoming film Guardians of the Galaxy Vol. 2, the Hubble Space Telescope has some amazing superpowers, specifically when it comes to observing galaxies across time and space. One stunning example is galaxy cluster Abell 370, which contains a vast assortment of several hundred galaxies tied together by the mutual pull of gravity. That's a lot of galaxies to be guarding, and just in this one cluster! […]

  • VISTA peeks through the Small Magellanic Cloud's dusty veil
    on May 3, 2017 at 12:02 pm

    VISTA's infrared capabilities have now allowed astronomers to see the myriad of stars in the Small Magellanic Cloud galaxy much more clearly than ever before. The result is this record-breaking image -- the biggest infrared image ever taken of the Small Magellanic Cloud -- with the whole frame filled with millions of stars. […]

  • Scientists find giant wave rolling through the Perseus galaxy cluster
    on May 2, 2017 at 6:24 pm

    Combining data from NASA's Chandra X-ray Observatory with radio observations and computer simulations, an international team of scientists has discovered a 200,000-light-year wave of hot gas in the Perseus galaxy cluster. […]

  • Supermassive black holes found in two tiny galaxies
    on April 17, 2017 at 6:49 pm

    Astronomers have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger galaxies. […]
