Scientist Finds 2-in-1 Burster: Pulsar Goes Off Twice Each Orbit

The US National Aeronautics and Space Administration's Marshall Space Flight Center recently announced the discovery of GROJ2058+42, an accreting X-ray pulsar with no visible component. The discovery was made by MSFC scientist Colleen Wilson while she was reviewing data obtained from the Burst and Transient Source Experiment (BATSE). The data showed that J2058+42 experiences two gamma ray bursts...

Chandra X-Ray Observatory Photo Album: G11.2-0.3 Chandra Associates Pulsar and Historic Supernova

NASA's Chandra X-Ray Observatory, designed to observe X-rays from high energy regions of the universe, regularly releases images taken using the Advanced CCD Imaging Spectrometer (ACIS). This image shows a pulsar located exactly at the geometric center of the supernova remnant known as G11.2-0.3. The image is accompanied by a table giving the scale, category, coordinates, observation date and...
