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.
