Experience Saturday’s annular solar eclipse at the Barlow Planetarium on the University of Wisconsin Oshkosh, Fox Cities campus.

“An annular solar eclipse is when the moon moves in front of the sun, but it is too far away from the Earth to completely cover the sun. It covers only the center of the sun, leaving the outer edges visible, which we call an annulus or a ‘ring of fire’,” said Teri Gee, Barlow Planetarium director.

A featured astronomy show called Eclipse: The Sun Revealed takes place at 10 a.m. Saturday, followed by solar eclipse viewing (weather permitting) from 10:30 a.m. to 1:15 p.m. A NASA livestream from the path of annularity will be shown from 10:45 a.m. to 12:45 p.m. Eclipse: The Sun Revealed will be shown again at 4 p.m.

“If the rain ends in time, we’ll have people outside to let you see the eclipse through telescopes with special filters,” Gee said.

Prices are $7 for children and seniors, $8 for students and $9 for adults. Eclipse glasses also will be available for sale.

The Barlow Planetarium, the first major planetarium in the state of Wisconsin, opened to the public on March 20, 1998. The 48-foot diameter projection dome with seating for 98 (in addition to four wheelchair accessible spaces) is powered by an Evans and Sutherland Digistar II, cutting-edge video projection and automation technology.

The planetarium offers a wide range of star and laser shows throughout the year.
