DESCRIPTION
In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars. Even when a planet is too far away to observe directly, scientists can infer its presence by watching for slight, regular dips in a star's brightness—when the planet orbits between its star and Earth, some of the star's light gets blocked from view. In this activity, participants perform a similar experiment, seeing what they can learn about a hidden object by studying its shadow.

OBJECTIVES
LEARNING GOALS
• Scientists are searching the universe for planets orbiting distant stars.
• When a planet, or other object, moves between its star and Earth, some light from that star gets blocked from view.
• The transit method is one of the ways NASA scientists search for distant planets.
