X-ray view of a thousand-year-old cosmic tapestry

Posted: 17 Apr 2013 01:50 PM PDT

A long Chandra observation reveals the SN 1006 supernova remnant in exquisite detail. By overlapping 10 different pointings of Chandra's field-of-view, astronomers have stitched together a cosmic tapestry of the debris field that was created when a white dwarf star exploded, sending its material hurtling into space as seen from Earth over a millennium ago. In this new Chandra image, low, medium, and higher-energy X-rays are colored red, green, and blue respectively.
