  • NASA's NuSTAR Telescope Discovers Shockingly Bright Dead Star (08 Oct 2014)
    Bachetti et al. (2014, Nature, 514, 202) used NuSTAR (together with Chandra and Swift) to find a pulsating "dead" star beaming with the energy of about 10 million suns. This is the brightest pulsar ever recorded. The surprising find is helping astronomers better understand the mysterious sources of blinding X-rays, called ultraluminous X-ray sources (ULXs), which, until now, were all thought to be black holes.
  • The Pulse of a Dead Star Powers Intense Gamma Rays (16 Sep 2014)
    When the most massive stars explode as supernovae, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains? NuSTAR is helping to untangle the mystery.

  • NuSTAR Sees Rare "Blurring" of Black Hole Light (12 Aug 2014)
    NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) has captured an extreme and rare event in the regions immediately surrounding the supermassive black hole in Markarian 335. A compact source of X-rays that sits near the black hole, called the corona, has moved closer to the black hole over a period of just days so that the black hole's intense gravity has blurred and stretched its X-ray emission.

  • Dead Star and Distant Black Holes Dazzle in X-Rays (09 Jan 2014)
    Two new views from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, showcase the telescope's talent for spying objects near and far. One image shows the energized remains of a dead star, a structure nicknamed the "Hand of God" after its resemblance to a hand. Another image shows distant black holes buried in blankets of dust.
  • Do Black Holes Come in Size Medium? (02 Dec 2013)
