Hubble captures a new portrait of Mars
NASA/ESA Hubble Space Telescope captured this stunning view of Mars on May 12, 2016, when Mars was 50 million miles from Earth.
The image showcases Mar’s frosty polar caps and clouds above a vivid, rust-colored landscape. The large, dark region at far right is Syrtis Major Planitia, an ancient, inactive shield volcano. Late-afternoon clouds surround its summit in this view.
The orange area in the center of the image is Arabia Terra, a vast upland region densely cratered and heavily eroded in northern Mars that covers about 2,800 miles. Dried river canyons wind through the region and empty into the large northern lowlands.
The icy northern polar cap has receded to a comparatively small size because it is now late summer in the northern hemisphere.
