July 21, 2014 - High-Energy Mission

High-Energy Mission The STS-93 mission, launched fifteen years ago this week with Eileen Collins at the helm, was the first shuttle mission commanded by a woman. During the five-day mission, the crew of Columbia deployed the Chandra X-Ray Observatory, one of NASA’s four Great Observatories. This image, combining data from Chandra and Hubble, shows N49, the aftermath of a supernova explosion in the Large Magellanic Cloud. High-energy X-ray data from Chandra, shown in blue, reveals evidence for a bullet-shaped object (at bottom) being blown out of a debris field left over from an exploded star. Optical data from Hubble (yellow and purple) shows bright filaments where the shock wave generated by the supernova is interacting with the densest regions in nearby clouds of cool, molecular gas.
