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 .

Contact with aliens within two decades

For two days, various specialists have gathered in Santa Clara to share ideas and explore possibilities to find, near future, life beyond Earth. Something that, by all accounts of the participants, could be about to happen.

Surprise! Mars is full of water

According to an article just published in the journal Geology, there is strong evidence indicating the existence of vast underground reserves of water on Mars.
