X-ray Images of M82 & SN2014J
New Chandra data gives insight into the explosion that produced SN 2014J, one of the closest supernovas discovered in decades. SN 2014J is a so-called Type Ia supernova, an important class that astronomers use to measure the expansion of the Universe. This image (left) shows M82 in the low, medium, and high-energy X-rays that Chandra can detect in red, green, and blue respectively. The images in the middle and right show close-up views of the region around the supernova in data taken prior to the explosion (middle), as well as data gathered about three weeks after the supernova went off (right). The lack of X-rays detected by Chandra rules out one mechanism that scientists theorized could cause the star to explode.
