on another world
the rays of the setting sun
are like an old friend

Sunset on Mars
The rover caught this stunning view of the sun setting over the rim of Gale crater on April 15, 2015. Unlike our red-hued sunsets, Martian views are tinted blue thanks to fine particles that allow more blue light into the atmosphere.
