A hidden ocean on Titan

The Cassini has shown that Titan, a satellite of Saturn, experiences significant tidal effects on its surface. In the course of its orbit, which lasts 16 days, changes shape: the closer is the gas giant tends to of a rugby ball while closer to a sphere at the farthest point from Saturn. This variation leads to a redistribution of mass and a change in the gravitational field. This is what Cassini measured, thanks to whose data has been concluded that in order to explain the tides experienced, Titan must have a liquid ocean, probably water under the surface.

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

Dozens of scholars have analyzed the possibilities of finding California, in the near future, life beyond Earth. We are better positioned than ever to detect life beyond Earth. And also to pick up signals of possible extraterrestrial intelligence, which will probably happen laspróximas over two decades.

These are some of the conclusions of the conference setIcon 2, held in Santa Clara, California, during the past weekend.

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.
