Mother Nature's Summer Blockbuster

August 21, 2017 is likely to be the most watched solar eclipse in human history. This solar eclipse will carve out a path of totality - where the view of the sun is completely covered by the moon - from Washington to South Carolina. In Michigan, we will observe roughly 85% totality. The eclipse will never be safe to observe with the naked eye.

What is a solar eclipse?

A solar eclipse happens when the moon casts a shadow on Earth, fully or partially blocking the sun’s light in some areas. Observers within the path of totality will be able to see the sun’s corona, weather permitting. Observers outside this path will see a partial eclipse. In Michigan, the moon will begin crossing the sun’s surface around 1:00 pm, with the point of greatest eclipse happening just before 2:30 pm, and leaving the surface of the sun shortly before 4:00 pm.

Eclipse Glasses

Eclipse glasses are available for $1 each in the Longway Planetarium gift shop. Protect your eyes during the solar eclipse! NEVER look directly at the sun without appropriate eyewear. Regular sunglasses are not sufficient protection. Click here to view NASA's eclipse safety guidelines.
