The distribution of valley heads on Mars matches predictions for a climate that includes precipitation rather than just runoff from melting ice caps.
A surprise discovery in Gale Crater is the component that was missing in the puzzle of Mars's climate history.
Once again, Mars has presented us with an example of something it seems to have in abundance: extremely peculiar and baffling rocks.
Martian dust storms can potentially cause respiratory issues and elevated risk of disease, making them yet another health hazard space agencies need to prepare for, according to new research.
The discovery is one of the most significant findings in the search for evidence of past life on Mars.
The mineral content of oddly pale rocks found in Jezero Crater can only have formed under very warm, very soggy conditions – suggesting that, long ago, Mars may have been a lot more peculiar than we ever suspected.
ESA's Hera mission for planetary defence made the first use of its payload for scientific purposes beyond Earth and the Moon. Activating a trio of instruments, Hera imaged the surface of the red planet as well as the face of Deimos.
Data from Chinese Zhurong rover provide an unprecedented look into rocks buried near a proposed shoreline billions of years old. The researchers claim to have found beach deposits from an ancient Martian ocean.
A new international study partially funded by NASA on how Mars got its iconic red color adds to evidence that Mars had a cool but wet and potentially habitable climate in its ancient past.
New images, taken over 16 min on January 17, 2025 by the Mastcam instrument on NASA's Curiosity rover, show noctilucent, or twilight clouds, in the atmosphere of Mars.
Meteoroids striking Mars produce seismic signals that can reach deeper into the planet than previously known.
Though it's a cold, dead planet, Mars still has its own natural beauty about it. This image shows us something we'll never see on Earth - Martian CO2 geysers.
We know that lakes existed on Mars’ surface billions of years ago. But scientists have debated whether the lakes were open to the air or covered by a layer of ice.
The southern highlands of Mars (which cover about two-thirds of the planet’s surface) rise as much as five or six kilometres higher than the northern lowlands. Nowhere else in the Solar System do we see such a large, sharp contrast at this scale.
The research suggests that the thick crust of Mars' southern highlands formed billions of years ago generated granitic magmas and sustained vast underground aquifers.
