N49: A supernova remnant located in the Large Magellenic Cloud
Caption: This composite image of data from Chandra (blue) and Hubble (yellow and purple) depicts the scene of a supernova explosionís aftermath. The X-ray data reveal a bullet-like structure to the lower right that appears to have been blown out of the remnant. The detection of the bullet, which is traveling at some 5 million miles per hour, is evidence that the explosion that created the remnant was not symmetrical.
