A geological mystery is revealed by Opportunity

Spherical objects focused on a projection that Opportunity reached fluctuate in several aspects of the iron-rich spherules nicknamed "blueberries" that the rover found in its place of landing in early 2004 and in many other places so far.

The crater Hadley gives a deep insight of the geology of Mars

Recently unavailable in supporting the successful landing of the Curiosity rover of the Mars Science Laboratory, NASA, ESA's Mars Express has now returned to its primary mission to study the varied geology and atmosphere "Red Planet" from orbit.

Earlier this year, the spacecraft observed the Hadley crater 120 km wide,

Hill, one of the most famous craters of the moon can be 5 to 10% water ice

The new approximation of the amount of water ice led to radar Mini-RF, on board the American "moon" of the probe LRO. The focus, as in many similar studies, focused on the Moon's south pole, where the deep crater Shackleton . These places are the most promising for the construction of this permanent manned base on the edge of the crater found a lovely flat landing area, and located very near to the "peak of eternal light", where the sun shines constantly, it would be convenient to install solar panels.

The oldest crater on Earth is in Greenland

European Geologists have found the oldest impact crater on Earth in the city of Maniitsog (Greenland). This is a crater 100 kilometers in diameter caused by the fall of an asteroid 3,000 million years ago. Experts suspected the existence of the crater since 2009, when the Geological Survey of Denmark and Greenland, examining a geological map of the surrounding Maniitsoq, discovered strange anomalies in the structure of the local rocks, caused by the impact of a giant meteor .

A low sun angle for a memorable view of a large Martian crater

NASA's Mars Exploration Rover Opportunity has used a low sun angle for a memorable view of a large Martian crater. The resulting view catches a shadow of the rover in the foreground and the giant basin in the distance. Opportunity is perched on the western rim of Endeavour Crater looking eastward.

The crater spans about 14 miles (22 kilometers) in diameter. Opportunity has been studying the edge of Endeavour Crater since arriving there in August 2011.The scene is presented in false color to emphasize differences in materials such as dark dunes on the crater floor. This gives portions of the image an aqua tint.

‘LAKE CHEKO’ IS THE IMPACT CRATER OF EVENT

They claim that Lake Cheko is the impact crater in the Tunguska Event. The observation by the team of Lake Cheko. Crà © dito: Geochemistry, Geophysics, Geosystems. / In the early hours of the MAA ± ana of June 30, 1908, occurred ³ a huge explosion in a remote part of Siberia near the Stony Tunguska River. So great was the explosion that knocks down trees ³ à ³ n in a circular patra s more than 2,000 km ³ ^ 2 and illuminates the sky from parts of Asia to Great Britain ± a. What causes this explosion ³ n has never been firmly resolved. The majority of researchers agree this was the result of a comet or meteoroid, with most leaning toward the former because of the lack of both an impact crater as a meteoroid fragments.

Tyco crater on the Moon

The Moon is still a goal for NASA; on June 10 last the satellite NASA Lunar Reconnaissance Orbiter was able to take this dramatic image thanks to its steep orbital angle of 65 °. The image is the central peak of the crater Tyco in the southern hemisphere of the Moon.Tyco is a place known to fans as it is one of the most outstanding places on the Moon. It is located at latitude 43.37 ° S, 348.68 ° E, and has about 82 kilometers in diameter.

The height of its central peak in the image above rises 2 km above the crater floor and the distance between the bases and is 4.7 km Comber.

The complex central peak of Tyco crater is about 15 km long and is easily visible with a backyard telescope. 

The Largest impact craters that have beaten the Earth

Imagine staring at the sky, which gradually gets closer, more and more closely. That point doubling in size every second, to darken the sky. His entry into the atmosphere is accompanied by light and heat, the giant rock wrapped in a meteor full of death that goes directly to you. 

It sounds like the introduction of a catastrophic film, however not very far from reality as these impacts ended the lives of potential witnesses to the event in his time, leaving only the record of their impact on Earth's surface. Today we will show the largest impact craters that have impacted the Earth. In ascending order according to their size, see:
