From studying the solar corona to providing precise measurements of the orbit of an object in deep space, scientists continue to develop new uses for eclipses and transit nearly every year. With the recent total solar eclipse across the United States, scientists and non-scientists alike have been captivated by the knowledge gained when one astronomical body passes in front of another. Eclipses and transits are not unique to the Sun, Earth, Moon and other bodies in our solar system. Similar phenomena occur between other stars and the planets and moons around them as well. It is possible to see transits of distant stars with telescopes on earth and satellites in space. Observing these phenomena provides a wealth of information about distant planetary systems. This presentation will describe three specific NASA projects that use shadows from eclipses and transits to shed new light on the cosmos.
