  • This image, taken by the newly installed Wide Field Camera 3, shows the Butterfly Nebula (or Bug Nebula, cataloged as NGC 6302), at the center of which is a dying star that once had five times the mass of Earth's sun. Gas that was released by a dying star shoots through space at a speed in excess of 600,000 miles an hour.
