Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes.
A new study from ETH Zurich geoscientists Giovanni Leone, however, suggests that lava, rather than water or tectonic plate activity, cut the gigantic valleys into the red planet's landscape.
The shared geological features found in U-shaped bedrock canyons both in south-central Idaho and on the surface of Mars are likely the result of massive floods, according to research appearing in the journal Proceedings of the National Academy of Sciences.
Ripped apart by tectonic forces, Hebes Chasma and its neighboring network of canyons bear the scars of the Red Planet’s early history.
Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning color movie from ESA's Mars Express.
Valles Marineris stretches over 4000 kilometers in length and is 200 kilometers wide, with a maximum depth of 10 kilometers. This makes it 10 times longer and five times deeper than the Grand Canyon, earning it the title of the largest canyon in the Solar System.
Scientists have reconstructed the formation of two curious features in the northern ice cap of Marsâ€”a chasm larger than the Grand Canyon and a series of spiral troughsâ€”solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars.
The U.S. space agency says its Mars Reconnaissance Orbiter has found evidence that liquid water remained on Mars far longer than previously theorized. The National Aeronautics and Space Administration spacecraft has observed hydrated silica, or opal, spread across large regions of Mars.
NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars.
Parts of ancient Mars may have been wet for a billion years longer than scientists previously thought, a new study of images of the red planet's surface suggests. Along with Earth and the other inner planets of our solar system, Mars formed about 4.5 billion years ago.
