Enormous polygon patterns in rock lie dozens of meters below Mars’ surface, ground-penetrating radar data suggest. Similar patterns develop on the surface in Earth’s polar regions when icy sediments ...

NASA’s Curiosity rover has detected more than 20 organic molecules, including DNA precursors, preserved in 3.5-billion-year-old Martian rocks, alongside large-scale polygon patterns linked to ancient ...

NASA’s Curiosity rover has uncovered over 20 types of ancient organic molecules in Gale Crater, including compounds linked to life’s building blocks, alongside vast ‘dragon skin’-like rock patterns.

PASADENA, Calif. — Climate cycles persisting for millions of years on ancient Mars left a record of rhythmic patterns in thick stacks of sedimentary rock layers, revealed in three-dimensional detail ...

These carefully-patterned rock arrangements look like something out of a meditation garden, or environmental art. But they are actually the product of simple computer algorithms expressed through a 3D ...
