NASA's powerful James Webb telescope has spotted a "surprisingly large" plume of water coming from the gas giant's sixth-largest moon Enceladus.

Scientists say that the plume spans for over 6,000 miles and is equivalent to the distance between Los Angeles and Buenos Aires.

Saturn has more than 100 known moons but Enceladus is the only one comparable to Earth as it has a liquid water ocean and experts are convinced that it could be home to a form of extraterrestrial life.

Geronimo Villanueva, from NASA's Goddard Space Flight Center in Maryland, said: "When I was looking at the data, at first, I was thinking I had to be wrong.

"It was just so shocking to detect a water plume more than 20 times the size of the moon."
