The remains of a supernova explosion form complex loops and filaments in this combined optical and X-ray image. N49, in the Large Magellanic Cloud, a small companion galaxy to the Milky Way, exploded about 5,000 years ago as seen from Earth. Today, it consists of a crushed stellar remnant known as a neutron star and a rapidly expanding cloud of hot gas. The X-ray observations (blue), by Chandra X-Ray Observatory, reveal a "bullet" of gas to the lower right of the nebula. The bullet, which was ejected in the explosion, is traveling at about 5 million miles per hour, suggesting that the explosion was lopsided, so material didn't expand evenly in all directions.
