WASHINGTON: Astronomers have spotted a small rocky planet that orbits perilously close to its host star disintegrating as its surface is vaporised by stellar heat, trailed by a comet-like tail of ...

“The shape of the transit is typical of a comet with a long tail,” said Marc Hon, another author of the study. “Except that it’s unlikely that this tail contains volatile gases and ice as ...

The scientists confirmed that the signal is of a tightly orbiting rocky planet that is trailing a long, comet-like tail of debris. "The extent of the tail is gargantuan, stretching up to 9 million ...

Astronomers have spotted a first-of-its-kind rapidly crumbling planet outside the Solar System that is leaving behind a “gargantuan” comet-like tail of debris. It is so close to its star that ...
