    Feature: Funky Light Signal From Colliding Black Holes Explained

    Entangled by gravity and destined to merge, two candidate black holes in a distant galaxy appear to be locked in an intricate dance. Researchers using data from NASA's Galaxy Evolution Explorer (GALEX) and NASA's Hubble Space Telescope have come up with the most compelling confirmation yet for the existence of these merging black holes and have found new details about their odd, cyclical light signal.

  • Planets Under a Red Sun

    Feature Story: NASA Telescope Ferrets Out Planet-Hunting Targets

    Astronomers have come up with a new way of identifying close, faint stars with NASA's Galaxy Evolution Explorer satellite. The technique should help in the hunt for planets that lie beyond our solar system, because nearby, hard-to-see stars could very well be home to the easiest-to-see alien planets.

  • NGC 4522

    Feature Story: Galactic Nature Vs. Nurture

    Just as psychologists have pondered the age-old question of "nature vs. nurture" in humans, astronomers are tackling a similar cosmic dilemma -- how much of a galaxy's development is due to innate characteristics, and how much is affected by the surrounding environment?
