Exoplanets as of September 2009

Exoplanets as of September 2009

Over 300 and counting! Earlier last week we saw the release of the first photos of a palnet around another star. Now the good people from the Keck telescope have released the first photo of a solar system. Three planets orbiting a star. The star, HR 8799,  in the image was blocked to avoid the glare so you could see the much dimmer planets.

This photo was taken in the infra-red part of the spectrum using adaptive optics. The three planets are estimated to be about 10 times the mass of Jupiter. A simiar photo to this was take by th Gemini Telescope.
