Newfound Exoplanet May Turn to Dust

Researchers at MIT, NASA and elsewhere have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris -- much like the tail of a comet -- is following the planet, and that this tail may tell the story of the planet's disintegration. According to the team's calculations, the tiny exoplanet, not much larger than Mercury, will completely disintegrate within 100 million years.
