Researchers using #JWST were able to catch an enormous water plume from Saturn’s icy moon Enceladus. The plume is more than 20 times the size of the moon. Enceladus orbits Saturn every 33 hours, spraying water and leaving behind a torus—or “donut”—of material in its wake.
So movie aliens, if you’re considering invading Earth to steal our precious water, I would suggest taking a detour to Saturn 😉

1. Animation of the Saturn system and its moons, Mimas, Enceladus, Tethys, Dione, Rhea and Titan, with arcs showing the orbits of the Moons. A blue ring surrounds the second moon Enceladus. Zoom into Enceladus. A large plume, much larger than the moon itself, is seen coming from the moon’s south pole. Next, a real JWST image is superimposed on the animation, titled “Water Pulme and Torus Model”. The image appears pixelated. A single, white pixel is labeled “Enceladus.” The dark background is labeled “Water Torus.” Below the pixel representing Enceladus is a roughly triangular-shaped area of brighter blue pixels, which is narrower near the moon and gets wider as it extends to the bottom of the image. This is labeled “Plume” near the moon and “Extended Plume” near the bottom. The JWST image fades out, and we zoom into a 3D model of Enceladus based on Casini images. A light grey moon with a few craters has four bright spots, plumes, just below its south pole. This shows us a detailed view of the area that is a single, bright pixel in the JWST image, and the source of the large plume seen by JWST.
