APOD: 2023 February 5 Б Enceladus by Saturnshine
Explanation:
This moon is
shining by the light of its
planet.
Specifically, a large portion of Enceladus
pictured here
is illuminated primarily by sunlight first reflected from the
planet Saturn.
The result is that the normally
snow-white moon appears in the gold color of
Saturn's cloud tops.
As most of the illumination comes from the image left, a
labyrinth
of ridges throws notable shadows just to the right of the image center,
while the kilometer-deep canyon
Labtayt Sulci is visible just below.
The bright thin crescent on the far right is the only part of
Enceladus directly lit by the Sun.
The
featured image
was taken in 2011 by the robotic
Cassini spacecraft during a close pass by by the
enigmatic moon.
Inspection of the lower left part of this digitally sharpened image reveals
plumes of ice
crystals thought to originate in a
below-surface sea.
