(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
(PhysOrg.com) -- An odd, previously unseen landform could provide a window into the geological history of Mars, according to new research by University of Washington geologists.
(PhysOrg.com) -- In addition to its rivers, oceans, mountains, sand dunes and winds, Saturns moon Titan may someday share another similarity with Earth: airplanes.
Some of the dark sandstone in an area being explored by NASA's Curiosity Mars rover shows texture and inclined bedding structures characteristic of deposits that formed as sand dunes, then were cemented into rock.
With its thick, hazy atmosphere and surface rivers, mountains, lakes and dunes, Titan, Saturn's largest moon, is one of the most Earthlike places in the solar system.
Mysterious dark sand dunes around Mars' northern polar cap are shifting with the seasons, as carbon dioxide gas changes form and sparks landscape-altering avalanches, said a study published Thursday.
Titan, Saturn's largest moon, is a peculiar place. Unlike any other moon, it has a dense atmosphere. It has rivers and lakes made up of components of natural gas, such as ethane and methane. It also has windswept dunes that ...
Kalahari. The name conjures an arid, almost lifeless expanse, its red, iron oxide sands stretching to the horizon and beyond.
Several gorgeous images are in this weeks update from the HiRISE camera on board the Mars Reconnaissance Orbiter. This lovely image shows the cliffs at the edges of huge ice sheet at the North Pole of Mars. These cliffs ...
