Within the calderas of the volcanoes, the water that swaps between the surface and atmosphere each day during cold Martian seasons could fill 60 Olympic-size swimming pools, about 150,000 tons of ...

Scientists have now identified water frost on the summits of several large Martian volcanoes, indicating potential habitable zones for future missions to the Red Planet. This discovery, led by Dr ...

A giant volcano has been found in Mars’ Tharsis plateau, making it the fourth known volcano in the region. Heavily eroded, the 29,600-foot (9,022-meter) volcano has been hiding in plain sight ...

Olympus Mons is the largest volcano in the Solar System, however, it’s not on Earth. The massive volcano is on the surface of ...

Scientists may have pinpointed a massive, oddly shaped volcano taller than Mount Everest on the surface of Mars — and it has been hiding in plain sight for decades, according to new research.

Near Mars’ equator, a giant volcano has been hiding from us for decades. While the site had been observed by spacecraft since the 1970s, the volcano’s severe erosion disguised it.

The team made the discovery by observing giant holes on Mars called calderas, which can stretch dozens of miles. These form when a volcano collapses after a super-eruption.

Using cameras fitted on probes orbiting Mars, researchers have observed morning frost forming inside the calderas of the planet’s volcanoes for the first time.

The planet Mars is known for its vast array of inactive shield volcanoes, and a new volcano could be added to the family with a recent study presented at the 55th Lunar and Planetary Science ...

Martian volcanoes are big but not numerous, making each new discovery significant. The Tharsis volcanic province is made up of a giant bulge, the most prominent geographic feature on Mars, with ...

Scientists may have pinpointed a massive, oddly shaped volcano taller than Mount Everest on the surface of Mars — and it has been hiding in plain sight for decades, according to new research.

A massive volcano may be hiding in plain sight on Mars, according to a report from two researchers that’s making waves in the planetary science community.
