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 ...

Since the 1970s, planetary geologists have known that volcanic features cover large swaths of Mars. Early Mariner 9 images ...

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.

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 ...

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, ...

New findings suggest that massive volcanoes played a pivotal role in shaping the early Martian landscape. We are about to explore the scientific evidence that supports this hypothesis and the ...

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 the complex geological processes responsible ...

A 2025 satellite photo captures the stark contrast between the barren Poás volcano and the surrounding Costa Rican jungle. The volcano's super-acidic lake provides the perfect analog for studying how ...
