Caption
Supernova (SN 2002dd) in the Hubble Deep Field / April 10 / 2003. Hubble Space Telescope observations of a pair of very distant exploding stars / called Type Ia supernovae / provide new clues about the accelerating universe and its mysterious "dark energy." Astronomers used the telescope's Advanced Camera for Surveys to help pinpoint the supernovae / which are approximately 5 billion and 8 billion light-years from Earth. The farther one exploded so long ago the universe may still have been decelerating under its own gravity.
