It's not a chance to glimpse celebrities on the South Lawn but the opportunity to look up and see the night sky.

The White House will serve as the backdrop for stargazing Wednesday as the President and First Lady host 150 middle school children for an evening of astronomy. The students will gaze at Jupiter, the moon, and select stars thru twenty telescopes and participate in hands-on activities involving model solar systems, meteorites and moon rocks.

Professional astronomists, NASA specialists and Sally Ride, the first American woman to travel into space, will join the First family as they celebrate World Space Week.
