Researchers based millions of kilometres from Mars have unveiled new evidence for how contemporary features are formed on the Red Planet. Their innovative lab-based experiments on carbon dioxide (CO2) sublimation – the process by which a substance changes from a … Continue reading
Research by planetary scientists at Brown University finds that periodic melting of ice sheets on a cold early Mars would have created enough water to carve the ancient valleys and lakebeds seen on the planet today. For scientists trying to … Continue reading
Alba Mons is the largest volcano, by area, on Mars. A low-lying volcano in the northern Tharsis region, Alba Mons has an elevation of 6.8 km, and volcanic flow fields that extend at least 1,350 km from the summit. Alba … Continue reading
In geology, an unconformity is a buried erosion surface, where the bedding layers don’t match. It doesn’t mean a mismatch in attitudes and beliefs, with rebellious behavior like streaking. But Mars does have streaking of a different kind, from the … Continue reading
Many slopes in the middle latitudes of Mars show icy flows or glaciers. The region shown here, in the south-facing slope of a crater, is unusual because the flows have bright highlights. The color and brightness variations are likely due … Continue reading
500-Meter circular feature or possible crater. Beautiful Mars series.
It is spring in the Northern hemisphere when we took this image. Over the winter, snow and ice have inexorably covered the dunes. Unlike on Earth, this snow and ice is carbon dioxide, better known to us as dry ice. … Continue reading
Within a crater in the Southern Highlands. This is a very ancient crater, long filled-in. You can see polygonal patterns in the terrain, mainly due to the contraction of subsurface ice as the seasons change. Beautiful Mars series.
THEMIS Image of the Day, June 15, 2017. Do you see what I see? Looks like the letter L, or maybe someone sitting down. (THEMIS Art #126) More THEMIS Images of the Day by geological topic.
On a field of sublimation – Sublimation is a process where a solid directly turns into a gaseous state. Beautiful Mars series.
