Aeolian bedforms are common on Earth and across the solar system, including on Mars, Venus, Pluto, the Saturn moon Titan, the Neptune moon Triton, and Comet 67P. These geological features, among the ...

A brand new lizard species with a hieroglyphic pattern on its back has been discovered among the sand dunes in eastern Iran. The discovery, which was detailed in a study in the journal Zootaxa on ...

Different wind patterns can cause different types of dune structures. Once that first mound forms, sand piles up on the windward side, or the side that is getting hit with the most wind.

On a nearby sand dune, researchers found 10 lizards with a unique pattern, the study said. They took a closer look and realized they’d captured a new species: Eremias graphica, or the ...

Researchers have analyzed the shifting patterns of entire dune fields on Earth and Mars, as seen from orbit, and found they are a direct signature of recent environmental change. This new tool can ...

“By comparing compound dunes on Mars to those on Earth, we can uncover similarities and differences that could help us better understand the Martian surface and atmosphere.” Image of Lauren Berger in ...

Wind can shape these miniature dunes in less than half an hour and blow them away just as quickly. Unlike the processes that form larger dunes that define desert landscapes and shorelines, those that ...

After that clay was formed, that’s when the sand dunes moved in around 3,500 years ago,” she said. To determine which sand is recent, scientists use optically stimulated luminescence.

As the sun beat down on a sand dune in Iran, a patterned creature rested in the shadow of a bush. Nearby scientists spotted the long-tailed animal — and discovered a new species. Researchers ventured ...
