| Astronomers were surprised to discover a 25-million-year-old protoplanetary disk around a pair of red dwarf stars 350 light-years away. Gravitational stirring by the binary star system (shown in this artist's conception) may have prevented planet formation. Credit: David A. Aguilar (CfA) |

Artist's conception of a possible collision around BD +20 307 that might have created some of the dust observed in the recent Gemini/ Keck observations. The collisions responsible for the dust could range in size from asteroids (approximated here) to planets the size of the Earth or Mars. Image Credit: "Gemini Observatory/Jon Lomberg

This exterior view of Mauna Kea highlights the Gemini North Observatory which is the largest dome near the center of the image. This image was taken shortly after a significant snowfall in early 1999 before skiers hit the slopes!

The Zodiacal Light as photographed from Mauna Kea shortly after the end of evening twilight. The wedge-shaped glow (whitish glow at center) is produced by the scattering of sunlight by the small amount of dust remaining from the formation of the solar system. In a system like BD +20 307 the density of the dust is thought to be about one-million times more dense than currently exists in our solar system to create this glow.
