They may resemble kidney beans, but formations on the northern hemisphere of Mars are actually sand dunes covered in carbon dioxide frost; How cold winters are on Mars depends on

Mars has northern and southern hemispheres like Earth, but their defining characteristics are markedly different, a phenomenon known as Martian dichotomy. The Southern Highlands are older, higher in elevation and more cratered than the Northern Lowlands.

So I grabbed my camera, ran outside, and looked up just as Mars was supposed to emerge from the Moon's curved horizon. Seen with the naked eye, the Moon's brightness far outshined Mars, casting soft shadows on a cold winter evening in East Texas.

Despite the cloudy skies and rain, some skygazers were able to catch a glimpse of Mars on Jan 16. Read more at straitstimes.com.

NASA’s Curiosity rover is skygazing and photographing lovely examples of noctilucent clouds on Mars. The wispy formations hang like a veil across the sky.

An exploding budget and an unraveling schedule spell disappointment for NASA's mission to learn more about Mars's history.

On Monday night you may have a chance to witness the moon obscuring the Red Planet at its brightest, as well as a comet’s closest approach to the sun.
