UCLA’s popular free moon viewing night will be held on Saturday, Oct. 5. Guests may view the moon through a high-powered, world-class telescope, and experts from UCLA’s departments of Earth, planetary and space sciences and of physics and astronomy will be on hand to answer questions.

The event, scheduled from 7 to about 9 p.m., will take place on the roof of UCLA’s Mathematical Sciences Building (map).

If skies are clear, viewers will be able to see the moon — approximately 240,000 miles from Earth — and its many craters in great detail. In addition, guests may get information about the astronomical body and examine meteorites and moon dust.

The festivities are part of International Observe the Moon Night, which began 10 years ago and has grown in popularity, with hundreds of events held on this night across the globe.

To get to the roof, enter the Mathematical Sciences Building from the Court of Sciences on the fifth floor and take the elevator to the ninth floor. Paid parking is available in Structure 2, at Hilgard and Westholme avenues, on the east side of the UCLA campus.

The event is presented by UCLA’s Institute for Planets and Exoplanets.
