A striking NASA/ESA Hubble Space Telescope near-infrared picture of a disk
around the star HD 141569, located about 320 light-years away in the
constellation Libra. Hubble shows that the 75 billion-mile wide disk
seems to come in two parts: a dark band separates a bright inner region
from a fainter outer region. The structure superficially looks much like
the largest gap in Saturn's rings - but on a vastly larger scale.
