  • Does dark matter annihilate quicker in the Milky Way?
    on June 23, 2017 at 2:04 pm

    A new theory predicts how dark matter may be annihilating much more rapidly in the Milky Way, than in smaller or larger galaxies and the early Universe. […]

  • Origins of Sun's swirling spicules discovered
    on June 22, 2017 at 9:14 pm

    For the first time, a computer simulation -- so detailed it took a full year to run -- shows how spicules form, helping scientists understand how spicules can break free of the sun's surface and surge upward so quickly. […]

    on June 22, 2017 at 2:40 pm

    The plane of the solar system is warped in the belt's outer reaches, signaling the presence of an unknown Mars-to-Earth-mass planetary object far beyond Pluto, according to new research.&nbs […]

  • Massive dead disk galaxy challenges theories of galaxy evolution
    on June 21, 2017 at 6:51 pm

    By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang. […]

  • Ten near-Earth size planets in habitable zone of their star
    on June 20, 2017 at 4:33 pm

    NASA's Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. […]

  • A unique data center for cosmological simulations
    on June 20, 2017 at 3:41 pm

  • Low-mass stars always born with a sibling: Many, like our sun, split up
    on June 14, 2017 at 1:19 pm

    Though astronomers have long known that many if not most stars are binaries, the question has always been, Were they born that way, or did one star capture another? Astronomers teamed up to systematically study very young stars inside their nest eggs, called dense cores, in the Perseus molecular cloud and concluded that all sunlike stars are born as wide binaries. Most subsequently split up, while the rest become tight binaries. […]

  • Search for Earth-like planets: Try a statistical approach
    on June 14, 2017 at 1:19 pm

    A team of astronomers seeks to change the way scientists approach the search for Earth-like planets orbiting stars other than the sun. They favor taking a statistical comparative approach in seeking habitable planets and life beyond the solar system. […]

  • Galaxy alignments traced back 10 billion years
    on June 13, 2017 at 3:16 pm

    The most massive galaxies in the universe have been aligned with their surroundings for at least ten billion years. This discovery shows that galaxies, like people, are influenced by their environment from a young age. […]

  • VST captures Eagle Nebula and close companions
    on June 13, 2017 at 2:21 pm

    Two of the sky's more famous residents share the stage with a lesser-known neighbor in an enormous new three gigapixel image from ESO's VLT Survey Telescope (VST). On the right lies Sharpless 2-54, the iconic Eagle Nebula is in the center, and the Omega Nebula to the left. This cosmic trio makes up just a portion of a vast complex of gas and dust within which new stars are springing to life and illuminating their surroundings. […]

  • Hubble applauds waltzing dwarfs
    on June 9, 2017 at 11:31 pm

    This seemingly unspectacular series of dots with varying distances between them actually shows the slow waltz of two brown dwarfs. The image is a stack of 12 images made over the course of three years with the NASA/ESA Hubble Space Telescope. Using high-precision astrometry, astronomers tracked the two components of the system as they moved both across the sky and around each other. […]

  • Century-old relativity experiment used to measure a white dwarf's mass
    on June 7, 2017 at 6:26 pm

    Astronomers have used the sharp vision of NASA’s Hubble Space Telescope to repeat a century-old test of Einstein’s general theory of relativity. The team measured the mass of white dwarf Stein 2051 B, the burned-out remnant of a normal star, by seeing how much it deflects the light from a background star. The gravitational microlensing method data provide a solid estimate of the white dwarf’s mass and yield insights into theories of the structure and composition of the burned-out star. […]

  • New confirmation of Einstein's General Theory of Relativity
    on June 7, 2017 at 4:38 pm

    Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending distant starlight. Yet, Einstein added, 'There is no hope of observing this phenomenon directly.' Now, researchers have done just that, saying that the discovery opens a new window to understanding 'the history and evolution of galaxies such as our own.' […]

  • Jackpot! Cosmic magnifying-glass effect captures universe's brightest galaxies
    on June 6, 2017 at 7:57 pm

    Boosted by natural magnifying lenses in space, NASA's Hubble Space Telescope has captured unique close-up views of the universe's brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky Way. […]

  • Mini-flares potentially jeopardize habitability of planets circling red dwarf stars
    on June 6, 2017 at 4:33 pm

    Solar flares and associated eruptions can trigger auroras on Earth or, more ominously, damage satellites and power grids. Could flares on cool, red dwarf stars cause even more havoc to orbiting planets, even rendering them uninhabitable? To help answer that question, astronomers sought to find out how many flares such stars typically unleash. […]

  • Hubble's tale of two exoplanets: Nature vs. nurture
    on June 5, 2017 at 7:45 pm

    Is it a case of nature versus nurture when it comes to two 'cousin' exoplanets? In a unique experiment, scientists used NASA's Hubble Space Telescope to study two 'hot Jupiter' exoplanets. Because these planets are virtually the same size and temperature, and orbit around nearly identical stars at the same distance, the team hypothesized that their atmospheres should be alike. What they found surprised them. […]

  • A planet hotter than most stars
    on June 5, 2017 at 3:09 pm

    A newly discovered Jupiter-like world is so hot that it’s stretching the definition of the word “planet.&rdquo […]

  • Cold brown dwarf discovered close to our solar system
    on June 2, 2017 at 3:28 pm

    A new citizen-science tool released earlier this year to help astronomers pinpoint new worlds lurking in the outer reaches of our solar system has already led to a discovery: a brown dwarf a little more than 100 light years away from the Sun. Just six days after the launch of the Backyard Worlds: Planet 9 website, four users alerted the science team to the curious object, whose presence has since been confirmed via telescope. […]

  • Giant ringed planet likely cause of mysterious eclipses
    on May 31, 2017 at 1:25 pm

    A giant gas planet -- up to 50x the mass of Jupiter, encircled by a ring of dust -- is likely hurtling around a star over 1000 light years away from Earth, according to international team of astronomers. […]

  • Do stars fall quietly into black holes, or crash into something utterly unknown?
    on May 30, 2017 at 3:51 pm

    Astronomers have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein's General Theory of Relativity. […]

  • Extreme Jupiter weather and magnetic fields
    on May 25, 2017 at 6:58 pm

  • The big star that couldn't become a supernova
    on May 25, 2017 at 6:15 pm

    For the first time in history, astronomers have been able to watch as a dying star was reborn as a black hole. It went out with a whimper instead of a bang. […]

  • Volunteers help find star that exploded 970 million years ago, predating the dinosaurs
    on May 24, 2017 at 2:15 pm
