Almost a century after a mysterious explosion in Russia flattened a huge swath of Siberian forest, scientists have found what they believe is a crater made by the cosmic object that made the blast. picked by AutumnLotus 1 year ago 1 comments edit related share plime.com |
A lake that might once have been habitable may have filled a crater for a long time on early Mars, new spacecraft images reveal. NASA's Mars Reconnaissance Orbiter captured the images that suggest the debris-strewn Holden Crater once held a calm body of water that could have harbored life. picked by AutumnLotus 9 months ago 3 comments edit related share science |
Geophysicists now have created the most detailed 3-D seismic images yet of the mostly submerged Chicxulub impact crater. The images show the crater contained sulfur-rich sediments that would have reacted with the water vapor to create sulfate aerosols. These compounds in the atmosphere would have made the impact deadlier by cooling the climate and producing acid rain. picked by AutumnLotus 10 months ago 1 comments edit related share science |
For the past 30 years or so an astounding renovation has been underway below roden crater, a 3km wide dormant volcano crater located northeast of Flagstaff in Arizona, the brilliance of which probably won't be apparent until the large-scale art installation opens when ready, apparently in 2012. picked by AutumnLotus 1 month ago 0 comments edit related share plime.com |

Located at Turkmenistan desert, Darvaza flaming crater is 60 meters in diameter and 20 meters depth and is not caused by volcanic activity or a meteorite impact. This crater was created sometime in the 50's when the Soviets were prospecting for natural gas in this area and it's been burning since then. picked by wildminou 9 months ago 3 comments edit related share world |

The crater is about 60 metres deep, allowing a rover to "dig" deeper into the ground – and into Mars's past – than ever before. "We're going to see more of the history of Mars here than we've seen anywhere else," Squyres says. picked by DrNothing 1 year ago 0 comments edit related share plime.com |
The possibility of an asteroid walloping the planet Mars this month is whetting the appetites of Earth-bound scientists, even as they further refine the space rock's trajectory. The space rock in question — Asteroid 2007 WD5 — is similar in size to the object that carved Meteor Crater into northern Arizona some 50,000 years ago and is approaching Mars at about 30,000 miles per hour (48... read full post picked by AutumnLotus 11 months ago 4 comments edit related share plime.com |

Researchers at the University of Massachusetts Amherst have discovered metal-rich sedimentary deposits in a New Hampshire lake that grow faster than any other deposits found in the United States. Understanding the environmental conditions that aid in the creation of the structures, which contain copper, iron and other heavy metals, could be helpful in discovering new metal sources. picked by AutumnLotus 1 year ago 0 comments edit related share plime.com |

There's a growing buzz in the astrobiology community that ancient hydrothermal springs may have been spotted on Mars. Thanks to the eagle-eyed work of Carlton Allen and Dorothy Oehler of NASA's Johnson Space Center, "spring-like" mounds have been found in Vernal Crater in Arabia Terra on the red planet. picked by AutumnLotus 7 months ago 1 comments edit related share science |

A spectacular megabreccia (a coarse rock assemblage composed of large angular-to-rounded fragments, some over 6m in length, held together by a mineral cement – in this particular case by melted rock in the form of fine crystalline glassy material) in the Kraaipan granite-greenstone terrane, located roughly midway between Mafikeng and Vryburg, has provided the first clues to the recognition o... read full post picked by AutumnLotus 1 year ago 5 comments edit related share plime.com |
