APOD: 2024 August 25 Б Fresh Tiger Stripes on Saturns Enceladus
25.08.2024

Do underground oceans vent through canyons on Saturn's moon Enceladus? Long features dubbed tiger stripes are known to be spewing ice from the moon's icy interior into space, creating a cloud of fine ice particles over the moon's South Pole and creating Saturn's mysterious E-ring.

APOD: 2025 June 10 Б Enceladus in True Color
10.06.2025

Do oceans under the ice of Saturn's moon Enceladus contain life? A reason to think so involves long features -- some dubbed tiger stripes -- that are known to be spewing ice from the moon's icy interior into space.
