The class of exotic Jupiter-mass planets that orbit very close to their parent stars were not explicitly expected before their discovery.

It’s a discovery that not only explains what’s happening to WASP-12b; it also means scientists have a one-of-a-kind opportunity to observe how a planet enters this final stage of its life.

The findings were published in the February 25 issue of Nature. (read more)
