In Supernova Remnant Spins One of the Youngest Pulsars Ever Seen

  Over fifty years ago, a supernova was discovered in Messier 83, a spiral galaxy about 15 million light years from Earth. Astronomers have used NASA’s Chandra X-ray Observatory to make the first detection of X-rays emitted by the debris from this explosion. This new Chandra image,released yesterday of M83 is one of the deepest X-ray observations ever made [continue reading]

Has the Speediest Pulsar Been Found?

  Researchers using three different telescopes — NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton in space, and the Parkes radio telescope in Australia — may have found the fastest moving pulsar ever seen. Pulsar IGR J11014-6103 in optical, infrared and X-ray. Credit: NASA The evidence for this potentially record-breaking speed comes, in part, from the [continue reading]
