Backlit Planet

Featured on September 16, 2016

This artist's concept of the planet known as HAT-P-11b shows how astronomers can discover and study the atmosphere of a planet in another star system. As the planet crosses in front of its star, some of the starlight passes through the planet's atmosphere. Analysis of the light can reveal the atmosphere's chemical composition. [NASA/ESA/JPL]
