Explanation: How different does sunset appear from Mars than from Earth? For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here side-by-side. A quick inspection will reveal that the Sun appears slightly smaller from Mars than from Earth. This makes sense since Mars is 50% further from the Sun than Earth. More striking, perhaps, is that the Martian sunset is noticeably bluer near the Sun than the typically orange colors near the setting Sun from Earth. The reason for the blue hues from Mars is not fully understood, but thought to be related to forward scattering properties of Martian dust. The terrestrial sunset was taken in 2012 March from Marseille, France, while the Martian sunset was captured last month by NASA's robotic Curiosity rover from Gale crater on Mars.

Spectacular image of a Martian sunset.

Never knew the Martian sunset was bluish.
What an incredible photo.
thank you,for all the visual goodies I enjoy on a daily basis.
I just noticed that there is an attenuated rainbow in the
Martian sunset at the right of the picture. It’s pretty.
The apparent sizes of the Sun are of interest as well,
proof positive that Mars is farther from the Sun, if
anyone had his doubts. :)
Thank you for the post and ping, Mr. Civilizations.
