New photos captured by NASA's Curiosity rover show that Mars' giant, spiderweb-like "boxwork" features are covered in tiny, never-before-seen nodules that bear a striking resemblance to arachnid ...

NASA’s Curiosity rover has just come face-to-face with a mystery that has haunted scientists from a distance for years. While orbital satellites first spotted strange, web-like patterns on the ...

Learn how water bears (tardigrades) reacted to simulated Martian regolith, what the results reveal about toxic compounds in ...

In this age of Mars rovers, questions about the planet's ancient past have shifted. A growing body of evidence supports the ...

Tardigrades, the microscopic “water bears” known for surviving space vacuum, extreme radiation, and freezing ...

NASA's Curiosity rover just found bizarre nodules on giant Martian "spiderwebs." Scientists are puzzled.

A potential new mineral on Mars forms when iron sulfates are heated above 100°C. Data from Valles Marineris regions suggest ...

A new study shows how simulated Mars dust affects tardigrades, offering insight into space farming and contamination risks.

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, ...

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.

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...
