JWST Discovers Massive Plume from Enceladus's Geysers.

The James Webb Space Telescope (JWST) has revealed the water plume from Enceladus's geysers is much bigger than previously thought, with the size of an outburst recorded as "immense". The discovery of geysers near the south pole of Saturn’s moon Enceladus rocketed the previously low-profile satellite to the top of planetary scientists’ priority list. The JWST's images could reveal something of the plume’s composition, potentially even including biosignatures.
