Video of NGC 6791

NGC 6791I've added a short video from NASA to the Star Viewer Map. The video looks at a recent Hubble telescope image of NGC 6791.

NGC 6791 is one of the oldest and largest open clusters known. The detection by Hubble 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.
