A new study by investigators at the Massachusetts Institute of Technology (MIT) manages to reveal the intricate and ancient history of the North American craton, a section of our planet's crust that has been around for a very long time, and that lies right in the middle of the continent.
Earth's rocky lay... |

Earlier this month, a strong volcanic eruption began taking place in the Red Sea. By December 19, fishermen reported seeing columns of lava rising as much as 90 feet (30 meters) above the waves. At this point, a new, barely-held-together island has appeared where there was only water before. The area is not necessari... |

The age of an impact crater has a tremendous influence on how the structure looks like to an external observer. The formation in this image, called the Bigach Impact Crater, is located in northeastern Kazakhstan, but its nature is not immediately visible from the ground.
Its interior is relatively flat, but the im... |

Throughout the world, the existence of U-shaped valleys featuring a distinct shape and composition have been attributed to the action of glaciers over millions of years. Recently, a team of scientists developed a model that can indicate how these areas looked like before the ices took hold. Glacier valleys are produc... |

One of the things the Swiss Alps are famous for is the impressive number of gorges they contain. These landscape features are monumental in scale and grandeur, and also very difficult for geologists to explain. A recent study proposes a new approach to explaining the gorges' existence. According to researchers b... |

In a groundbreaking new success, researchers managed to observe for the first time the vertical evolution of a major mountain range. The research was conducted on the Southern Alps of New Zealand. It only took a decade of accurate GPS measurements for researchers to become able to figure out this mystery. The high-pr... |

Scientists have for a long time wondered as to why certain mid-continental fault lines rupture even when they are not sited directly atop tectonic plate boundaries. Such is the case for example with the New Madrid fault line, which lies southwest from New Madrid, Missouri. Oftentimes, it produces what are known as in... |

Geologists and climatologists have been aware that global warming and climate change have been eroding the Alaskan coastline for many years, but they have been unsure of the extent of the damage until recently. After using a camera to snap a series of time-lapse photos, they are now able to conclude that the Alaskan ... |

Scientists at the University of Minnesota announce the development of a new and unique computer model, designed to assist experts in reverting real streams to initial, healthier states. The program, which has been dubbed the Virtual StreamLab, demonstrates the physical of natural water flows with unprecedented realis... |

The European Space Agency's Mars Express orbiter has recently snapped a new series of photos of the planet's surface, revealing scarred terrain stretching for large distances, as well as several impact craters, most likely caused by asteroids that struck the planet in the past. An area roughly the size of M... |

A new survey of a 64-kilometer (40-mile) stretch of the Beaufort Sea, in Alaska, shows that soil erosion has nearly doubled in speed and intensity over the past five years, between 2002 and 2007. This discovery has numerous important implications, including the destruction of the natural habitat of the animals and th... |

The number of scientific devices studying the red planet is continuously on the rise. This adds to the constant discovery of unusual features sported by Mars, eventually providing more insight on its formation, evolution and structure. More recent images captured by the Mars Reconnaissance Orbiter (MRO)'s High R... |

A water jet cutter is a tool able to slice into various solid materials with the help of a high speed jet containing a mixture of water and an abrasive material. Basically, water jet cutters rely on the same process that shaped most of the surface of the planet over the course of the past several billion years, water... |

Unlike most of the individual celestial bodies in the universe, which tend to take the shapes of spheres (the geometrical object with minimum surface area in relation to volume), asteroids come practically in all the possible shapes and sizes, although why this happens remained largely unknown until now. By studying ... |

Back on 13 April 2007, during its 4199 orbit around the Red Planet, ESA's Mars Express took an image of the Terby crater, with the help of its High Resolution Stereo Camera. It seems to be presenting high scientific interest, mainly because it could hold valuable information about the role of liquid water in the... |

Jason Buelterman, Tybee Insland's Mayor, posted a clip on the famous online video sharing service YouTube in a desperate attempt to show the local beach erosion and get some help from the authorities. It seems that the mayor aimed to attract Georgia's Congressional Delegation because they represent the only... |
