  • Viewing tool updated (22 Jul 2014)
    The Swift pole constraints have been updated in the Viewing tool. The revised coefficients extrapolate the trend for the next year. The web interface has also been enhanced with improved error handling.
  • NASA's Chandra X-ray Observatory Celebrates 15th Anniversary (22 Jul 2014)
    Fifteen years ago, the Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. To celebrate its 15th anniversary, four new images of supernova remnants, the Crab Nebula, Tycho, G292.0+1.8, and 3C58 , are being released.
  • Fermi Finds A 'Transformer' Pulsar (22 Jul 2014)
    In late June 2013, an exceptional binary containing a rapidly spinning neutron star, the 1.7-millisecond pulsar named PSR J1023+0038, underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the most powerful form of light, according to measurements by the Fermi Gamma-Ray Space Telescope.
  • 2XMMi/SDSS Galaxy Cluster Survey (21 Jul 2014)
    This catalog listing the X-ray and optical properties of 145 X-ray-detected clusters of galaxies (Takey et al. 2014, A&A, 564, A54) is now available in Browse and Xamin.
  • Chandra Cycle 16 Accepted Proposals and Targets Lists Are Now Available (17 Jul 2014)
    The peer-review recommended targets and proposals for Chandra Cycle 16 for regular, large, multicycle and XVP-type programs, as well as the approved joint proposals with other ground-based and/or satellite facilities, theory proposals and archive proposals, have been released.
  • Low-Frequency Radio Catalog of Flat-Spectrum Sources (LORCAT) (16 Jul 2014)
    This catalog of 28,358 radio sources with flat spectra between 325/352 MHz and 1400 MHz (from Massaro et al. 2014, ApJS, 213, 3) is now available in Browse and Xamin.
