Saturn's moon Mimas drifts along in its orbit against
the azure backdrop of the planet's northern latitudes in this true color view.
The long, dark lines on the atmosphere are shadows cast by the planet’s
rings.
Saturn’s northern hemisphere is presently relatively
cloud-free and rays of sunlight take a long path through the atmosphere. This
results in sunlight being scattered at shorter (bluer) wavelengths, thus giving
the northernmost latitudes their bluish appearance at visible
wavelengths.
At bottom, craters on icy Mimas (398 kilometers, 247
miles across) give the moon a dimpled appearance.
Images taken using infrared (930 nanometers), green
(568 nanometers) and ultraviolet (338 nanometers) spectral filters were
combined. The colors have been adjusted to match closely what the scene would
look like in natural color. See PIA06142 for a similar view in natural
color.
The images were obtained using the narrow angle
camera on January 18, 2005, from a distance of approximately 1.4 million
kilometers (870,000 miles) from Saturn. Resolution in the image is 8.5
kilometers (5.3 miles) per pixel on Saturn and 7.5 kilometers (4.7 miles) per
pixel on Mimas. The image has been contrast-enhanced to aid
visibility.
