(A–B) Locations of mapped dune fields on (A) Earth and (B) Mars. (C–D) Examples of mapping and interaction identification on (C) linear dunes in Tanami Desert, Australia, and (D) crescentic dunes at ...

Despite its dry, dusty surface and thinner atmosphere, Mars may have more in common with Earth than scientists previously thought. In a new study, researchers at the University of Rochester—including ...

Scientists have discovered a new, persistent pattern in Earth's inner radiation belt using data from the twin NASA Van Allen Probes spacecraft. Most surprisingly, the pattern is produced by the slow ...

New research published in the journal Geoscience Frontiers highlights the cyclic patterns of geologic activity on Earth. Scientists from New York University report findings from an analysis of major ...

In the early days of photography, getting an aerial shot of a landscape meant attaching a camera, with a timer, to a balloon. That’s no longer necessary. These days, a bird’s eye view of the entire ...

In an analysis of the past 1.2 million years, UC Santa Barbara geologist Lorraine Lisiecki discovered a pattern that connects the regular changes of the Earth's orbital cycle to changes in the Earth's ...

Dunes, the mounds of sand formed by the wind that vary from ripples on the beach to towering behemoths in the desert, are incarnations of surface processes, climate change, and the surrounding ...

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 be ...
