MUSEUM CAMPUS — Haven't decided where to watch the solar eclipse Monday?
Try Adler Planetarium, which is throwing a free big block party.
Admission will also be free Monday inside the Adler at 1300 S. Lake Shore Drive. It's celebrating the rare phenomenon by handing out safety glasses and blowing up a big bounce house on its lawn for the first total solar eclipse visible from the United States since 1979.
A solar eclipse occurs when the moon gets between the sun and the Earth, casting a shadow on the world's surface.
On Monday, the moon will block out the midday sun for three minutes, and up to 87 percent of the sun will be covered in Chicago. The next total solar eclipse visible from Chicago won't be seen until 2099.
Guests can check out the Adler's new "Chasing Eclipses" exhibit Monday, and see a live feed of cities such as Nashville and Downstate Carbondale that sit along the eclipse's "path of totality" during the party, too.
The planetarium's regular sky shows will be offered at a discounted price of $5, and a special eclipse show inside the planetarium will be available for $2.
The planetarium opens at 9:30 a.m. Monday. The eclipse begins at 11:54 a.m. and climaxes at 1:19 p.m.
