For a total eclipse to take place, the sun, moon and Earth must be in a direct line. During a total solar eclipse, the moon blocks the sun’s glare, making the sun’s corona more visible. (NEVER look at the sun during any type of solar eclipse! Looking at the sun is dangerous. It can damage your eyes.) Image Credit: Steve Albers, Dennis DiCicco and Gary Emerson
