  • Seeing the light of neutron star collisions
    on October 16, 2017 at 4:21 pm

    When two neutron stars collided on Aug. 17, a widespread search for electromagnetic radiation from the event led to observations of light from the afterglow of the explosion, finally connecting a gravitational-wave-producing event with conventional astronomy using light, according to an international team of astronomers. […]

  • Hubble observes source of gravitational waves for the first time
    on October 16, 2017 at 4:21 pm

    The NASA/ESA Hubble Space Telescope has observed for the first time the source of a gravitational wave, created by the merger of two neutron stars. This merger created a kilonova -- an object predicted by theory decades ago -- that ejects heavy elements such as gold and platinum into space. This event also provides the strongest evidence yet that short duration gamma-ray bursts are caused by mergers of neutron stars. […]

  • Radio 'eyes' unlocking secrets of neutron-star collision
    on October 16, 2017 at 2:28 pm

    When a pair of superdense neutron stars collided and potentially formed a black hole in a galaxy 130 million light-years from Earth, they unleashed not only a train of gravitational waves but also an ongoing torrent of radio waves that are answering some of the biggest questions about the nature of such a cataclysmic event. […]

  • First observations of merging neutron stars mark a new era in astronomy
    on October 16, 2017 at 2:28 pm

    After LIGO detected gravitational waves from the merger of two neutron stars, the race was on to detect a visible counterpart, because unlike the colliding black holes responsible for LIGO's four previous detections, this event was expected to produce an explosion of visible light. Researchers have now found the source of the gravitational waves, capturing the first images of the event with the Swope Telescope in Chile. […]

    on October 11, 2017 at 5:55 pm

    On Oct. 12 EDT (Oct. 11 PDT), a small asteroid designated 2012 TC4 will safely pass by Earth at a distance of approximately 26,000 miles (42,000 kilometers). This is a little over one tenth the distance to the Moon and just above the orbital altitude of communications satellites. This encounter with TC4 is being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network. […]

  • Giant exoplanet hunters: Look for debris disks
    on October 11, 2017 at 5:52 pm

    There's no map showing all the billions of exoplanets hiding in our galaxy -- they're so distant and faint compared to their stars, it's hard to find them. Now, astronomers hunting for new worlds have established a possible signpost for giant exoplanets. […]

  • Scientists discover one of the most luminous 'new stars' ever
    on October 11, 2017 at 4:03 pm

    on October 4, 2017 at 11:05 pm

    In 2015, a star called KIC 8462852 caused quite a stir in and beyond the astronomy community due to a series of rapid, unexplained dimming events. The latest findings from astronomers take a longer look at the star, going back to 2006 -- before its strange behavior was detected by Kepler. […]

  • The super-Earth that came home for dinner
    on October 4, 2017 at 6:45 pm

    It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side. It is a possible "Planet Nine" -- a world perhaps 10 times the mass of Earth and 20 times farther from the sun than Neptune. […]

  • Surface helium detonation spells end for white dwarf
    on October 4, 2017 at 6:01 pm

    Researchers have found evidence that the brightest stellar explosions in our Universe could be triggered by helium nuclear detonation near the surface of a white dwarf star. […]

  • Farthest active inbound comet yet seen
    on September 28, 2017 at 7:23 pm

    NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit). Slightly warmed by the remote Sun, it has already begun to develop an 80,000-mile-wide fuzzy cloud of dust, called a coma, enveloping a tiny, solid nucleus of frozen gas and dust. These observations represent the earliest signs of activity ever seen from a comet entering the solar system's planetary zone for the first time. […]

  • Supersonic gas streams left over from the Big Bang drive massive black hole formation
    on September 28, 2017 at 6:20 pm

    A super-computer simulation by an international team of researchers has shown the formation of a rapidly growing star from supersonic gas streams in the early universe left over from the Big Bang. The star ends its life with catastrophic collapse to leave a black hole with a mass of 34,000 times that of the Sun. […]

  • Bursting with starbirth
    on September 28, 2017 at 2:12 pm

    This oddly shaped galactic spectacle is bursting with brand new stars.

  • Black holes with ravenous appetites define Type I active galaxies
    on September 27, 2017 at 5:36 pm

    Type I and Type II active galaxies do not just appear different -- they are, in fact, very different from each other, both structurally and energetically, new research shows. According to the results of a new study, the key factor that distinguishes Type I and Type II galaxies is the rate at which their central black holes -- or active galactic nuclei -- consume matter and spit out energy. […]

  • The strange structures of the Saturn nebula
    on September 27, 2017 at 1:33 pm

    The spectacular planetary nebula NGC 7009, or the Saturn Nebula, emerges from the darkness like a series of oddly-shaped bubbles, lit up in glorious pinks and blues. This colourful image was captured by the MUSE instrument on ESO's Very Large Telescope (VLT). The map -- which reveals a wealth of intricate structures in the dust, including shells, a halo and a curious wave-like feature -- will help astronomers understand how planetary nebulae develop their strange shapes and symmetries. […]
