On August 21, 2017, a total solar eclipse will be visible in parts of the United States for the first time since 1979. In Chicago, at 11:54 am CST, the Moon will start to block our view of the Sun, covering up to 87 percent of it by 1:19 p.m. The last time Chicago was this close to the path of totality (when the Moon blocks the Sun completely) was 92 years ago in 1925. In celebration, the Adler Planetarium is throwing a giant block party, inviting everyone to come together to experience this rare celestial event as a community, and making it possible by offering free general admission to all.
