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.
