When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

How did young volcanoes on Mars form? This is what a recent study published in the journal Geology hopes to address as a team of scientists investigated th | Space ...

A Martian volcano once thought to be the result of a single eruption turns out to have a much more complex past. Orbital imaging and mineral data show it developed through multiple eruptive phases, ...

Olympus Mons, a shield volcano on Mars, is the largest volcano in the solar system, measuring approximately 370 miles in diameter and 26 kilometers in height. The formation of Olympus Mons and three ...

Mars Without Tectonics: A Lava-built Monument The staggering height and volume of Olympus Mons are explained in part by Mars’s lack of tectonic plate movement. Unlike Earth, where shifting plates ...
