The Hubble Space Telescope was more than 1 billion miles away
from Saturn when it snapped this image. The dark band in the ring
system is actually a large gap between the rings called the Cassini
division. The gap was discovered in 1675 by Italian astronomer
Jean-Dominique Cassini, for whom the Cassini spacecraft is named.
The colors in the Hubble view are what you would see if you could
travel to the planet. The bright icy particles that make up the
rings make them appear white.
