  • Astrophysicist find supermassive black holes in quasar nearest Earth
    27 August 2015, 9:45 pm
    Astrophysicists have found two supermassive black holes in Markarian 231, the nearest quasar to Earth. The discovery of two supermassive black holes -- one larger one and a second, smaller one -- are evidence of a binary black hole and suggests that supermassive black holes assemble their masses through violent mergers.
  • Interstellar seeds could create oases of life
    27 August 2015, 5:16 pm
    Astrophysicists now show that if life can travel between the stars (a process called panspermia), it would spread in a characteristic pattern that we could potentially identify.
  • Discovering dust-obscured active galaxies as they grow
    27 August 2015, 2:35 pm
    Astronomers have performed an extensive search for Dust Obscured Galaxies (DOGs). The research group discovered 48 DOGs, and has measured how common they are. Since DOGs are thought to harbor a rapidly growing black hole in their centers, these results give us clues for understanding the evolution of galaxies and supermassive black holes.
  • Twin Jet Nebula: The wings of the butterfly
    26 August 2015, 4:20 pm
    The shimmering colours visible in this NASA/ESA Hubble Space Telescope image show off the remarkable complexity of the Twin Jet Nebula. The new image highlights the nebula's shells and its knots of expanding gas in striking detail. Two iridescent lobes of material stretch outwards from a central star system. Within these lobes two huge jets of gas are streaming from the star system at speeds in excess of one million kilometers per hour.
  • Earth's extremes point the way to extraterrestrial life
    26 August 2015, 4:16 pm
    Astrobiologists draw upon what is known about Earth's most extreme lifeforms and the environments of Mars and Titan, Saturn's moon, to paint a clearer picture of what life on other planets could be like.
  • Dying star suffers 'irregular heartbeats'
    26 August 2015, 2:21 pm
    Some dying stars suffer from ‘irregular heartbeats.' The research confirms rapid brightening events in otherwise normal pulsating white dwarfs, which are stars in the final stage of their life cycles.
  • Origin of Saturn’s F ring and its shepherd satellites revealed
    21 August 2015, 2:34 pm
    Scientists have revealed that Saturn's F ring and its shepherd satellites are natural outcome of the final stage of formation of Saturn's satellite system.
  • A detector shines in search for dark matter
    20 August 2015, 8:48 pm
    Results of the XENON100 experiment are a bright spot in the search for dark matter. The team of international scientists involved in the project demonstrated the sensitivity of their detector and recorded results that challenge several dark matter models and a longstanding claim of dark matter detection.
  • New data from Antarctic detector firms up cosmic neutrino sighting
    20 August 2015, 6:57 pm
    Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos.
  • NASA: There is no asteroid threatening Earth
    20 August 2015, 2:38 pm
    Numerous recent blogs and web postings are erroneously claiming that an asteroid will impact Earth, sometime between Sept. 15 and 28, 2015. However, NASA experts say that there is no scientific basis that an asteroid or any other celestial object will impact Earth on those dates.
