Saturn
has a fresh new look thanks to NASA’s Webb Space Telescope. The gas giant is dark in the latest photo by Webb, released Friday, but its icy
rings are glowing. Webb snapped the picture in the infrared
last weekend. At this wavelength
, the planet appears dark because sunlight is absorbed
by methane
in the atmosphere. But the icy rings remain bright. Three of Saturn’s many moons also got caught on camera.
