Twin Keck Telescopes Probe Dual Dust Disks

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 this artist’s rendition of 51 Ophiuchi’s inner and outer dust disks illustrates the size difference of their constituent grains.
