On August 21, 2017, Indiana University and the Bloomington Community will have the chance to witness the exciting phenomenon of a partial solar eclipse (since Bloomington is not in the direct line of the total solar eclipse)! Even though we will not be able to see a total solar eclipse, it is still exciting, important, and overall interesting to learn about eclipses, and how they work! So let's answer the ultimate question: what exactly is a solar eclipse?
