The south polar region of Mars When it was shared: Jan. 29, 2025 Why it's so special: These odd, fan-like features on the ...

NASA researchers have identified geological structures on Mars that are unlike anything found on Earth. From spider-like ...

Except for the scraps frozen into the polar caps, its water was lost to space or stored away as subsurface ice. And this all happened billions of years ago. The early Mars had been dynamic ...

The above image shows a 20-meter-long chunk of frozen carbon dioxide falling off a cliff. Rising temperatures during the ...

Martian clouds are almost always made of dry ice, or frozen carbon dioxide. 95% of the planet's atmosphere is CO2.

The new research, published in Geophysical Research Letters, revealed two large bands – or belts – of water ice located less than one meter below the Martian surface around Mars’ polar regions.

"Even the largest floods we modeled couldn't reach far enough to explain all the rootless cones we see." New data is challenging what scientists previously knew about one of the youngest ...

Like Earth, Mars has polar ice caps, volcanoes, canyons and deserts. This image was stitched together from a series of photos from the Viking Orbiter — one of the communications relay stations ...

Scientists have found vast oceans of ice lying just below the surface of Mars in a major boost to the search for alien life on the Red Planet. One of the most exciting planetary discoveries ever ...

Why it's so special: These odd, fan-like features on the surface of Mars are geysers of gas and dust near the planet's south pole that are visible only in springtime on the Red Planet. This image ...

"The current and past locations of water ice are an important piece of the history of Mars," Colin Dundas, a research geologist with the U.S. Geological Survey told Space.com. "Understanding this ...
