A group of investigators from the NASA Jet Propulsion Laboratory (JPL), in Pasadena, California, says that the High Resolution Imaging Science Experiment (HiRISE) instrument aboard the Mars Reconnaissance Orbiter (MRO) was recently used to image amazing landscapes on the surface of Mars.
HiRISE is one of the most ca... |

New data sent back by the NASA Mars Reconnaissance Orbiter (MRO) spacecraft indicate that Martian sand dunes are constantly shifting their positions, most likely under the influence of strong winds and a restless atmosphere.
This phenomenon is not isolated, researchers say, since instances of it occurring have been... |

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... |

Scientists with the Purdue University say that large urban concentrations are known to cause disturbances in massive thunderstorms hitting them. Their newest research demonstrates that the areas located downwind from these cities experience the effects of these modifications.If passing over a city changes the structu... |

Astronomers recently conducted a series of studies meant to provide additional insights into the nature of the Southern Equatorial Belt on Jupiter. The formation disappeared a year ago, and is currently making itself visible again. Planetary scientists are very interested in learning why the atmospheric structure is ... |

More than a decade ago, two major Antarctic ice shelves collapsed into the waters of the Southern Ocean, in an event that marked the seriousness of global warming with a real-life event. Now, experts are beginning to understand how various factors conspired to underlie the collapse. The western parts of Antarctica ar... |

A group of investigators has recently demonstrated that nearly all evidence of the fact that the twin Martian rovers Spirit and Opportunity has been deleted from the surface of the planet. Unlike the Moon, tracks left here can easily be destroyed by winds and sand storms.
This is not only possible, but also very ... |

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... |

According to a new scientific study, it would appear that the Red Sea may have been parted by winds blowing in a very specific way, rather than by the cane-wielding Moses. The data goes against the teaching contained in the Book of Genesis, which holds that the prophet Moses parted the Red Sea to allow for the fleeti... |

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... |

Ever since the time of Benjamin Franklin, kites have been used as scientific equipments in a variety of simple and complex tasks. This has been owed to the fact that they are inexpensive to operate, and also capable of carrying a fair amount of sensing equipment given sufficient wind to lift it up. Sensors are even t... |

Using its High Resolution Stereo Camera (HRSC) instrument, the European Space Agency's (ESA) Mars Express orbiter collected this amazing image of a Martian crater, back in 2005. Since then, experts have been analyzing it on all sides, in hopes of extracting new information about the intricate puzzle that is the ... |

A collaborative scientific effort, featuring researchers from the United States and Australia, has recently made a very interesting discovery in the Southern Ocean. It would appear that winds in this area have the ability to trigger variations in the deepest layer of surface water responsible for regulating the way i... |

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. ... |

When they were first discovered, snow rolls, or snow pipes as they are also called, were thought to be the work of aliens, pranksters or some undiscovered species of animals building a nest. But subsequent studies of the peculiar structures have revealed that they are all-natural, and also that they most often appear... |

The ten-year-old QuikSCAT (Quick Scatterometer) NASA mission is considered by many at the American space agency and elsewhere as one of the most valuable national resources in orbit today. The satellite, whose goal was to provide up-to-date data on the direction and speed of winds over the planet's oceans, was o... |

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... |

After centuries of wondering whether the winds on the distant gas giant Saturn move East or West, scientists and astronomers finally have their answer. It would appear that the atmosphere favors movements in both directions, a groundbreaking find that may help astronomers gain more insight into the properties of the ... |

Wind-powered electricity generators have been criticized for their unreliability since they first appeared, in that they are only able to produce variable amounts of current, when the wind flows strongest. Despite recent innovations in the technology, such as using lasers to assess wind direction and to improve wind ... |

Everyone knows that one of the most distinctive features of any desert is the sand dune, a large pile of sand that gives the location its wave-like aspect. These dunes regularly grow to be from a few feet to tens of feet in height, but some of them, the giant sand dunes, can even reach 1,600 feet (590 meters), or eve... |

Scientists at the University of York in UK discovered evidence of a line that they labeled "chemical equator," and which separates the northern hemisphere of the planet from its southern counterpart, in terms of pollution. The discovered line is 30 miles (50 km) wide and resides in the cloudless sky of the Weste... |

Due to the fact that Mars is about half the diameter of the Earth and has a gravity about six times weaker than ours, the Red Planet has a relatively thin atmosphere compared to our own. The researchers show that, for a sand dune to move across the Martian surface just a meter, it might take up to 1,000 years, mostly... |
