Scientists caught Saturn's icy moon Enceladus spraying a "huge plume" of watery vapor far into space — and that plume likely contains many of the chemical ingredients for life. 

Scientists detailed the eruption — glimpsed by the James Webb Space Telescope (JWST) in November 2022 — at a conference at the Space Telescope Science Institute in Baltimore on May 17.
