  • The Astro-H Launch Scheduled for Today Has Been Postponed (12 Feb 2016)
    Due to unfavorable weather, the Astro-H launch has been postponed. See this JAXA Press Release for more details.
  • Gravitational waves detected 100 years after Einstein's prediction (12 Feb 2016)
    For the first time, scientists have observed ripples in the fabric of space-time called gravitational waves, arriving at Earth from a cataclysmic event in the distant universe, namely the merger of two black holes to produce a single, more massive spinning black hole. This finding confirms a major prediction of Albert Einstein's 1915 general theory of relativity and opens an unprecedented new window to the cosmos.
  • Scientists to Provide Update on the Search for Gravitational Waves (11 Feb 2016)
    100 years after Einstein predicted the existence of gravitational waves, the National Science Foundation gathers scientists from Caltech, MIT and the Laser Interferometer Gravitational-wave Observatory (LIGO) Scientific Collaboration to update the scientific community on their efforts to detect them. The findings will be released at 10:30am today EST and are expected to be revolutionary.
  • HEASoft 6.18 Released (10 Feb 2016)
    Released February 6, 2016. This release features updates to the Swift/XRT software and compatibility of a new set of analysis software for the Astro-H mission pre-launch testing, and updates to other packages...
  • XMM-Newton SAS v15.0.0 Released (05 Feb 2016)
    The latest release of the XMM-Newton Science Analysis Software.
  • Pictor A: Blast from Black Hole in a Galaxy Far, Far Away (02 Feb 2016)
    To obtain images of the jet from the central super-massive black hole in the active galaxy Pictor A, Hardcastle et al. (2016, MNRAS, in press) used NASA's Chandra X-ray Observatory at various times over 15 years. Chandra's X-ray data have been combined with radio data from the Australia Telescope Compact Array to allow a detailed study of the spatial, temporal and spectral properties of the AGN, jet, hotspot and lobes.
