In the latest issue of the magazine NATURE astronomers report the first observation of an evaporating extrasolar planet, its atmosphere boiling off into space. Much of the planet may eventually disappear, leaving only a dense core. This observation sheds new light on the fate of gas giant planets that spiral in close to their parent stars, drawn to them like moths to a flame.

A team of astronomers used the Earth-orbiting NASA/ESA Hubble Space Telescope to observe the planet as it crossed the face of its parent star. The observations were made in ultraviolet light. Hubble's position above the atmosphere makes it the only telescope that can per
