Astronomers using the twin 10-meter telescopes at the W. M. Keck Observatory in Hawaii have explored one of the most compact dust disks ever resolved around another star. If placed in our own solar system, the disk would span about four times Earth's distance from the sun, reaching nearly to Jupiter's orbit. The compact inner disk is accompanied by an outer disk that extends hundreds of times farther.
