1. Optical and X-ray Images of NGC 1365
QuicktimeMPEG Beginning with the optical image of NGC 1365, the view then changes to reveal Chandra's image of the central region. The bright source in the middle of the X-ray image is generated by a disk of gas about to fall into a supermassive black hole. When a dense cloud within NGC 1365 passed in front of the black hole and disk, high-energy X-rays from the disk were blocked. This allowed astronomers to measure the size of the disk.
