Remains of devoured planet discovered

The dusty remains of a distant planet show what happens to a gas giant if it survives a red giant explosion

A DUST cloud around a dead star may be all that鈥檚 left of a planet that was eaten like a peach.

Observations of the cloud around the white dwarf G29-38 by a team led by William Reach of the California Institute of Technology in Pasadena suggest it is most likely to be the shredded core of a gas-giant planet like Jupiter (, in press).

The planet鈥檚 outer layers were apparently engulfed by the star鈥檚 preceding red giant phase. The core survived but may have been dragged close enough to the subsequent white dwarf to be torn apart by its gravity, creating the dust cloud.

Earth, on the other hand, is likely to be totally vaporised during the sun鈥檚 red giant phase billions of years from now.
