  • Black hole hunters tackle a cosmic conundrum
    20 April 2015, 8:44 pm
    Astrophysicists have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.
  • Pulsing light may indicate supermassive black hole merger
    20 April 2015, 4:10 pm
    As two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a 'binary,' or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.
  • Scaled-up version of our solar system 130 light-years away
    20 April 2015, 2:51 pm
    Astronomers has obtained the first results from the LEECH exoplanets survey. The findings reveal new insights into the architecture of HR8799, a 'scaled-up' version of our solar system 130 light-years from Earth.
  • Cold Spot suggests largest structure in Universe: A supervoid 1.3 billion light years across
    20 April 2015, 2:47 pm
    In 2004, astronomers examining a map of the radiation left over from the Big Bang discovered the Cold Spot, a larger-than-expected unusually cold area of the sky. The physics surrounding the Big Bang theory predicts warmer and cooler spots of various sizes in the infant universe, but a spot this large and this cold was unexpected.
  • Giant galaxies die from the inside out: Star formation shuts down in the centers of elliptical galaxies first
    16 April 2015, 8:11 pm
    Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago. Astronomers have revealed that three billion years after the Big Bang, these galaxies still made stars on their outskirts, but no longer in their interiors. The quenching of star formation seems to have started in the cores of the galaxies and then spread to the outer parts.
  • Intense magnetic field close to supermassive black hole
    16 April 2015, 8:10 pm
    Astronomers have revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole.
  • Dwarf planet Ceres color map reveals surface diversity
    16 April 2015, 7:56 pm
    A new color map of dwarf planet Ceres, which NASA's Dawn spacecraft has been orbiting since March, reveals the diversity of the surface of this planetary body. Differences in morphology and color across the surface suggest Ceres was once an active body.
  • NASA’s New Horizons Spacecraft Nears Historic July 14 Encounter with Pluto
    15 April 2015, 7:19 pm
    NASA's New Horizons spacecraft is three months from returning to humanity the first-ever close up images and scientific observations of distant Pluto and its system of large and small moons.
  • Northern lights: How 'black' auroras actually work
    15 April 2015, 3:09 pm
    While our understanding of how the aurora's shimmering curtains of colour are formed, scientists have struggled to explain the black patches between the bright beams. Now scientists have discovered what happens at the heart of these so-called "black aurora". 
  • First signs of self-interacting dark matter? Dark matter may not be completely dark after all
    15 April 2015, 3:21 am
    For the first time dark matter may have been observed interacting with other dark matter in a way other than through the force of gravity. Observations of colliding galaxies have picked up the first intriguing hints about the nature of this mysterious component of the Universe.
