American astronomers may have taken the first photograph of a planet outside our solar system. Susan Terebey of the Extrasolar Research Corporation in California and colleagues used the Hubble Space Telescope to photograph the object 450 light-years away in the Taurus constellation. Previous discoveries of extrasolar planets have relied on 'indirect' evidence such as the gravitational influence of the planet on its parent star. The findings will be presented at the American Astronomical Society meeting in San Diego next week.
