Unless you plan to be around in 2117, you may not want to miss this upcoming astronomical phenomenon.
On Tuesday, June 5, the planet of Venus will cross the sun and will be visible from a large portion of the United States. Over the hill, Foothill College's observatory and NASA Ames will have free viewings, open to the public.
"The Venus Transit is indeed a rare event, and full of historical lore," says the website of the Peninsula Astronomical Society, which will be running the Foothill viewing that begins at 3:30 p.m. and ends at 7 p.m.
NASA Ames invites the public to watch a live broadcast at 3:04 p.m. from the Exploration Center as Venus first makes its appearance in Mauna Kea, Hawaii.
