Giant clusters of crescent-shaped sand dunes found not just on Earth but on other planets in the solar system might emerge when large dunes give birth to smaller ones, researchers say. Subscribe to ...

Researchers have been studying the dynamics of how crescent-shaped sand dunes are formed. Known as barchans, these formations are commonly found in various sizes and circumstances, on Earth and on ...

Scientists have devised a new way to study winds on Mars by examining sand dunes on the planet’s surface. The resulting wind map could help explain recent changes in the martian climate and provide ...

image: Researchers at the University of Campinas conducted more than 120 experiments with dunes of up to 10 cm that interact for a few minutes, obtaining a model valid for dunes on the surface of Mars ...

Crescent-shaped dunes known as barchans can grow up to 100 metres in length, but researchers have never found one shorter than ten metres. This minimum length is thought to arise from an interaction ...

One would expect a complicated answer to such a complex question. So when a group of physicists achieved their first successful computer simulation of the dynamics of a Brazilian coastal dune field ...

to form a long dune ridge. The horns and attendant slip faces on these dunes indicate wind transport of sand from the upper left toward the lower right. The image is located near 77.6°N, 103.6°W. The ...

WASHINGTON, Dec. 6, 2022 – The English poet William Blake famously implored readers to "see the world in a grain of sand." In Physics of Fluids, by AIP Publishing, scientists from the University of ...
