Mission controllers at the NASA Jet Propulsion Laboratory say that the Mars Reconnaissance Orbiter has revealed surprising dune motion patterns on the Red Planet. Sand masses were found to move in similar patterns to those on Earth, even though the atmospheres surrounding the two planets are very different from one a... |

Saturn's largest moon, Titan, is of great interest to astronomers because it's the most Earth-like object in the solar system. One of the most recent studies conducted on the body was aimed at surveying its dunes using radars, and experts say that this allowed them to learn more about the moon's past c... |

Recent investigations conducted on a patch of desert in southern California revealed the existence of four types of sand dunes in the large erg called the Algodones Dunes. The fact that such a heterogeneous amalgamation of features exist in a relatively small space puzzles geologists.
The presence of the erg itsel... |

A new series of scientific observations, carried out from aboard a satellite, have revealed some interesting clues to the history of a series of dunes that mark the landscape in the state of Idaho.For most people, the landscape is nothing more than a good view, at times, and a daily occurrence at other times. Very fe... |

One of the most interesting things about Saturn's largest moon Titan is the array of dunes that adorns its surface. Given that there's sand and dunes, it stands to reason that the structures were produced by winds blowing in a certain direction. When the first atmospheric models of the celestial body were c... |

A new series of observations from Martian orbit have brought up another one of the Red Planet's mysteries. Scientists have noticed that, at some locations, sand dunes are actively moving under the influence of strong winds, constantly changing their location. Conversely, at other locations, the same dunes have r... |

Some of the most commonly known features on Mars are the planet's hills, which appear to have been shaped by winds. Astronomers and geologists argue had argued for a long time that this was the case, but it later on became obvious that atmospheric models and on-site rover measurements did not support this idea. ... |

The linear dunes that have been observed on the surface of Saturn's largest moon, Titan, have made astronomers wonder how they came to be since day one. A number of theories on their formation was proposed, some with no merit, and others that actually stand to reason even now. To these ideas, Louisiana State Uni... |

Engineers have recently unveiled a plan that a few years back might have seemed like a joke – to build a wall to mark the spread of the Sahara desert, so that the dunes stop spreading over yet-unaffected ground. The problem appears all over the Saharan borders, as fields and families are being displaced by the ... |

NASA's Mars Reconnaissance Orbiter took lately a couple of pictures of the Martian surface revealing some sand dunes, on the Hellespontus region of the planet, looking strikingly similar to a series of hoofmarks. According to NASA, such surface formations have also been spotted on Earth and are called barchan du... |
