Planets Outside Solar System
3/2/11

From images taken by NASA's Hubble Space Telescope, for This is the first time astronomers have spotted a planet orbiting a star outside our solar system which located 25 light-years away from Earth . The first photos of planets outside our Solar System have been take by two teams of astronomers who published them on Thursday.

The two teams used different ways to obtain photos of planets outside our Solar System. The team led by Mr. Macintosh used two ground-based telescopes, while the other team, led by Paul Kalas of the University of California, Berkeley, used photos from the Hubble Space Telescope.

The planet, Fomalhaut b, maintains an orbit around the star Fomalhaut and has three times the mass of Jupiter.
"Our Hubble observations were incredibly demanding. Fomalhaut b is 1 billion times fainter than the star. We began this program in 2001, and our persistence finally paid off," said Hubble astronomer Paul Kalas, of the University of California at Berkeley.
