This movie takes a closer loook at Hubble's image of NGC 6791, one of the oldest and largest open clusters known. The detection of white dwarfs that vary in age leads astronomers to rethink the theory that stars found in these clusters develop at the same time from large clouds of interstellar dust and gas.
