Abstract

Light from an alien planet For the first time, light from a planet outside our Solar System has been detected on Earth. The planet is HD 209458b, previously identified by the wobble its gravity induces in its host star's orbit. It is slightly larger than Jupiter, but orbits its star at less than a twentieth of the distance between the Earth and the Sun, making it a so-called ‘hot Jupiter’ planet. As HD 209458b passes behind the star, the amount of infrared light coming from the area drops slightly: that drop represents the planet's light contribution.
