  • Double or nothing: Astronomers rethink quasar environment
    on March 13, 2018 at 1:30 pm

    Astronomers have identified nearly 200 'protoclusters,' the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known. They also found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars. […]

  • Amateur astronomer captures rare first light from massive exploding star
    on February 21, 2018 at 6:18 pm

    First light from a supernova is hard to capture; no one can predict where and when a star will explode. An amateur astronomer has now captured on film this first light, emitted when the exploding core hits the star's outer layers: shock breakout. Subsequent observations by astronomers using the Lick and Keck observatories helped identify it as a Type IIb supernova that slimmed down from 20 to 5 solar masses before exploding. […]

  • NASA's James Webb Space Telescope to reveal secrets of the Red Planet
    on February 20, 2018 at 5:47 pm

    Mars rovers and orbiters have found signs that Mars once hosted liquid water on its surface. Much of that water escaped over time. How much water was lost, and how does the water that’s left move from ice to atmosphere to soil? During its first year of operations, NASA’s James Webb Space Telescope will seek answers. Webb also will study mysterious methane plumes that hint at possible geological or even biological activity. […]

  • Astronomers reveal secrets of most distant supernova ever detected
    on February 20, 2018 at 3:24 pm

  • TRAPPIST-1 planets probably rich in water
    on February 5, 2018 at 6:43 pm

    A new study has found that planets orbiting the star TRAPPIST-1 are made mostly of rock, and some could hold more water than Earth. The planets' densities suggest that some of them could have up to 5 percent of their mass in the form of water. The hotter planets closest to their parent star are likely to have dense steamy atmospheres and the more distant ones probably have icy surfaces. […]

  • Atmospheres of exoplanets in TRAPPIST-1 habitable zone probed
    on February 5, 2018 at 4:33 pm

    Astronomers using the Hubble Space Telescope have conducted the first spectroscopic survey of the Earth-sized planets within the habitable zone around the nearby star TRAPPIST-1. Hubble reveals that at least three of the exoplanets (d, e, and f) do not seem to contain puffy, hydrogen-rich atmospheres similar to gaseous planets such as Neptune. The results, instead, favor more compact atmospheres like those of Earth, Venus, and Mars. […]
