  • Universe may face a darker future: Is dark matter swallowing up dark energy?
    31 October 2014, 1:20 pm
    New research offers a novel insight into the nature of dark matter and dark energy and what the future of our Universe might be. Scientists have found hints that dark matter, the cosmic scaffolding on which our Universe is built, is being slowly erased, swallowed up by dark energy.
  • Planet discovered that won't stick to a schedule
    30 October 2014, 6:33 pm
    For their latest discovery, astronomers have found a low-mass, low-density planet with a punctuality problem. The new planet, called PH3c, is located 2,300 light years from Earth and has an atmosphere loaded with hydrogen and helium. Its inconsistency kept it from being picked up by automated computer algorithms that search stellar light curves and identify regular dips caused by objects passing in front of stars.
  • Hubble sees 'ghost light' from dead galaxies
    30 October 2014, 6:29 pm
    The universe is an infinite sea of galaxies, which are majestic star-cities. When galaxies group together in massive clusters, some of them can be ripped apart by the gravitational tug of other galaxies. Astronomers using the Hubble Space Telescope to probe the massive galaxy cluster Abell 2744 — nicknamed Pandora's Cluster — have found forensic evidence of galaxies torn apart long ago. It's in the form of a phantom-like faint glow filling the space between the galaxies. This glow comes from stars scattered into intergalactic space as a result of a galaxy's disintegration.
  • When did galaxies settle down?
    30 October 2014, 3:12 pm
    Astronomers have long sought to understand exactly how the universe evolved from its earliest history to the cosmos we see around us in the present day. In particular, the way that galaxies form and develop is still a matter for debate. Now a group of researchers have used the collective efforts of the hundreds of thousands of people that volunteer for the Galaxy Zoo project to shed some light on this problem. They find that galaxies may have settled into their current form some two billion years earlier than previously thought.
  • Planet-forming lifeline discovered in a binary star system
    29 October 2014, 7:12 pm
    Scientists have detected a streamer of dust and gas flowing from a massive outer disk toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disk of planet-forming material that otherwise would have disappeared long ago.
  • Planck 2013 results: Special feature describes data gathered over 15 months of observations
    29 October 2014, 2:54 pm
    Astronomy & Astrophysics is publishing a special feature of 31 articles describing the data gathered by Planck over 15 months of observations and released by ESA and the Planck Collaboration in March 2013. This series of papers presents the initial scientific results extracted from this first Planck dataset.
  • NASA statement regarding Oct. 28 Orbital Sciences Corp. Launch mishap
    29 October 2014, 4:05 am
    The following statement is from William Gerstenmaier, Associate Administrator of NASA's Human Exploration and Operations Directorate, regarding the mishap that occurred at Pad 0A of the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia during the attempted launch of Orbital Sciences Corp's Antares rocket and Cygnus cargo spacecraft at 6:22 p.m. Tuesday, Oct. 28.
  • Moon mission: Images of LADEE's impact crater captured
    29 October 2014, 2:41 am
    NASA's Lunar Reconnaissance Orbiter spacecraft has spied a new crater on the lunar surface; one made from the impact of NASA's Lunar Atmosphere and Dust Environment Explorer mission.
  • Laser experiments mimic cosmic explosions and planetary cores
    28 October 2014, 5:26 pm
    Researchers are finding ways to understand some of the mysteries of space without leaving earth. Using high-intensity lasers focused on targets smaller than a pencil's eraser, they conducted experiments to create colliding jets of plasma knotted by plasma filaments and self-generated magnetic fields, reaching pressures a billion times higher than seen on earth.
  • Tremendously bright pulsar may be one of many
    27 October 2014, 3:04 pm
    A newly found pulsar, the brightest ever seen, raises questions about a mysterious category of cosmic objects called ultraluminous X-ray sources. A member of the team that announced the discovery now discusses the likelihood of additional ultra-bright pulsars and considers how astrophysicists will align this new find with their understanding of how pulsars work.
