Astronomers spot an enormous hydrogen cloud trailing behind a distant planet

Thanks to the ultraviolet light-reading abilities of the Hubble Telescope, astronomers have spotted a massive hydrogen cloud that's trailing behind a distant planet.

The gaseous mass is so enormous they've named it "The Behemoth." Though the cloud is big, it doesn't necessarily indicate a large problem. Researchers believe it's simply a result of the Neptune-sized planet that's orbiting close to its sun. That kind of radiation often causes atmospheric hydrogen to evaporate.

In the case of this planet, however, its parent star isn't powerful enough to completely obliterate the gas, resulting in the formation and lingering of "The Behemoth."

In addition to being pretty fascinating to look at, one of the astronomers in the study believes it will usher in the discovery of many more planets of its kind.

Further, the ultraviolet-light observation method the team employed could be useful in finding surface oceans on faraway worlds.
