The Copernicus Sentinel-3A satellite takes us over the Gulf. Also known as the Arabian Gulf and the Persian Gulf, this marginal sea of the Indian Ocean is just under 1000 km long and covers an area of around 250 000 sq km. ...

Taking the temperature of protoDUNE

When crane operators at CERN lowered a custom 7.5-metre thermometer into one of the prototypes for the planned Deep Underground Neutrino Experiment (DUNE) earlier this month, it looked like a silver straw sliding into a giant ...

Study reveals how sand dunes alter seismic waves

Sand dunes may be lovely to behold, but they have long been seismic troublemakers to geophysicists trying to detect what lies underground nearby. A new study takes a stab at figuring out just how dunes are fouling seismic ...

Scientists discover 'ghost dunes' on Mars

Scientists have discovered hundreds of crescent-shaped pits on Mars where sand dunes the size of the U.S. Capitol stood billions of years ago. The curves of these ancient dune impressions record the direction of prevailing ...

New study details geological process behind Titan's dunes

Titan's windswept dunes may sprawl millions of more kilometers than previously thought and were likely formed by geological processes similar to those on Earth, according to a new study. The new findings could help scientists ...

A theoretical analysis of sand mega-ripples

A team of researchers from several institutions in Germany and Israel has used theoretical analysis to explain the conditions under which mega-ripples form in areas where sand dunes rise. In their paper published in the journal ...

Image: The case of the Martian boulder piles

This image was originally meant to track the movement of sand dunes near the North Pole of Mars, but what's on the ground in between the dunes is just as interesting!
