  • 'Failed stars' host powerful auroral displays
    29 July 2015, 8:21 pm
    By observing a brown dwarf 20 light-years away using both radio and optical telescopes, astronomers have found that such so-called failed stars host powerful auroras near their magnetic poles -- additional evidence that brown dwarfs are more like giant planets than small stars.
  • Dense star clusters shown to be binary black hole factories
    29 July 2015, 8:20 pm
    The merger of two black holes is one of the most sought-after observations of modern astronomy. The first observatories capable of directly detecting gravitational waves -- ripples in the fabric of spacetime predicted by Albert Einstein -- will begin observing the universe later this year. When these waves rolling in from space are detected on Earth for the first time, astrophysicists predict astronomers will 'hear,' through these waves, five times more colliding black holes than previously expected.
  • Secrets of stars unlocked through aluminium
    29 July 2015, 4:21 pm
    Physicists have revealed a new understanding of nucleosynthesis in stars, providing insight into the role massive stars play in the evolution of the Milky Way and the origins of the Solar System.
  • First detection of lithium from an exploding star
    29 July 2015, 2:59 pm
    The chemical element lithium has been found for the first time in material ejected by a nova. Observations of Nova Centauri 2013 made using telescopes at ESO's La Silla Observatory, and near Santiago in Chile, help to explain the mystery of why many young stars seem to have more of this chemical element than expected.
  • Lobster-eye imager detects soft X-ray emissions
    28 July 2015, 5:07 pm
    A group of scientists have described developing and launching their imager, which centers on "Lobster-Eye optics," as well as its capabilities and future applications in space exploration.
  • Dust pillars of destruction reveal impact of cosmic wind on galaxy evolution
    27 July 2015, 6:03 pm
    Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of how it happens.
  • Brown dwarfs, stars share formation process, new study indicates
    23 July 2015, 6:54 pm
    The discovery of jets of material ejected from still-forming brown dwarfs provides the first direct evidence that these enigmatic objects form in the same way as their more-massive siblings, stars, rather than like planets.
  • Bigger, older cousin to Earth discovered
    23 July 2015, 5:57 pm
    NASA's Kepler mission has confirmed the first near-Earth-size planet in the "habitable zone" around a sun-like star. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another "Earth."
  • Treasure hunting in archive data reveals clues about black holes’ diet
    23 July 2015, 2:38 pm
    Using archival data from the Sloan Digital Sky Survey, and the XMM-Newton and Chandra X-ray telescopes, astronomers have discovered a gigantic black hole, which is probably destroying and devouring a big star in its vicinity. With a mass of 100 million times more than our Sun, this is the largest black hole caught in this act so far.
  • Space-eye-view could help stop global wildlife decline
    22 July 2015, 8:14 pm
    Conservation scientists need to collaborate with space agencies, such as NASA and the European Space Agency, to identify measures which help track biodiversity declines around the world. Scientists are calling for urgent cooperation.
