Natural phenomena such as the Aug. 21, 2017 solar eclipse can inspire awe, but scientists can also use eclipse-like events to learn more about the universe. For instance, a total eclipse, or an occultation in scientific terms – happens when a celestial body completely blocks light from a star, like our sun. This type of event can help astronomers learn more about an object’s atmosphere, including whether it might be surrounded by rings or other planetary matter. During a similar event, called a transit, variations in light that result when a closer object passes in front of a star, but only blocks a small part of the star, have been used by missions such as our Kepler space telescope, to discover new planets outside our solar system.
