Water vapour plume seen jetting from Saturn’s moon Enceladus: NASA

Researchers have detected a water vapour plume jetting from Saturn's moon Enceladus using NASA's Webb telescope. "It was...so shocking to detect a water plume more than 20 times the size of the moon," NASA's Goddard Space Flight Center's Geronimo Villanueva said. The rate at which the vapour is gushing out is enough to fill an Olympic-sized swimming pool in hours.
