Over a millenia ago Earth witnessed an explosion in the heavens, that explosion was later discovered to be a supernova. Now, new data from NASA’s Chandra X-ray observatory adds to the awesome factor of SN 1006 and supernovae like it, which provides new details about the remains of this exploded star. As noted in Chandra’s official site:
“The Chandra data provides the best map to date of the debris field including information on important elements expanding into space.”
A new image of SN 1006 from NASA’s Chandra X-ray Observatory reveals this supernova remnant in exquisite detail. By overlapping ten 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. In this new Chandra image, low, medium, and higher-energy X-rays are colored red, green, and blue respectively.
The Chandra image provides new insight into the nature of SN1006, which is the remnant of a so-called Type Ia supernova . This class of supernova is caused when a white dwarf pulls too much mass from a companion star and explodes, or when two white dwarfs merge and explode. Understanding Type Ia supernovas is especially important because astronomers use observations of these explosions in distant galaxies as mileposts to mark the expansion of the Universe.
