Eye Spy a Planet: Hubble’s Universe Unfiltered

In 2008, Hubble released the first visible-light picture of a planet around another star. Planets around distant stars are extremely difficult to visualize — astronomers usually find them by observing the dimming of light as a planet passes in front of a star, or the wobble of the star as its tugged by the planet’s gravity.

“Hubble’s Universe” is a recurring broadcast from HubbleSite, online home of the Hubble Space Telescope. Astrophysicist Frank Summers takes viewers on an in-depth tour of the latest Hubble discoveries. Find more episodes at HubbleSite.org.
