NASA has captured a breathtaking image of Arsia Mons, one of Mars' most massive volcanoes, towering nearly twice the height of any mountain on Earth. Captured at dawn by the 2001 Mars Odyssey ...

Arsia Mons, an ancient Martian volcano, was captured before dawn on May 2, 2025, by NASA’s 2001 Mars Odyssey orbiter while the spacecraft was studying the Red Planet’s atmosphere, which ...

The photograph, snapped at dawn by NASA’s 2001 Mars Odyssey orbiter, offers an ethereal view of Arsia Mons, a massive Martian volcano rising through the planet’s early morning cloud cover.

A Martian volcano breaks through the clouds in a spectacular image captured by the Odyssey orbiter. This unprecedented view reveals Arsia Mons, one of Mars' largest volcanoes, emerging from a sea ...

Arsia Mons is the southernmost volcano in a group of three massive Martian volcanoes known collectively as Tharsis Montes. Until now, the volcano’s history has remained a mystery.

It must have been a pretty remarkable eruption, too, as the volcano is an incredible 270 miles wide and 12 miles high. Mauna Loa, Earth's largest volcano, is only 6.3 miles high and 75 miles across.

Mars once had a robust volcanic past, but NASA research shows Arsia Mons was last active around 50 million years ago, about the time when dinosaurs went extinct on Earth.

Microbial life could potentially have thrived for a time at the foot of Arsia Mons, a giant volcano about twice as tall as Mt. Everest, while the dinosaurs were just coming into their own on Earth ...

Because of its cloud cover, Arsia Mons has been hard to photograph. This new image from NASA's 2001 Mars Odyssey orbiter gives a first-of-its kind view at the peak of the volcano.

Arsia Mons is the southernmost of the three volcanoes that make up Tharsis Montes, shown in the center of this cropped topographic map of Mars. Olympus Mons, the solar system’s largest volcano ...
