The Depths of ocean Europe

 Found proof that the ocean in Europe, Jupiter, and a captive under a layer of ice has an exit to the surface.

The mission of Galileo (1989-2003) bring a lot of scientist’s important data about Jupiter and its moons, but the on-board infrared spectrometer probe was not able to identify all the parts needed to refine the mineral composition of the surface of Europe. Now, using a spectrometer OSIRIS (Keck Observatory, Hawaii), the researchers have made an interesting discovery.

Kepler-68b, a new type of planet

There are three types of planets in our solar system. On the one hand we have rocky worlds like Earth and Mars have a solid surface on which to put your feet and consist of 'rocks' (silicates and metals). Then there are gas giants like Jupiter and Saturn, composed mainly of hydrogen and helium (and actually should be called "Giant fluid" because most of its interior hydrogen is a liquid or metallic). Finally we have the ice giants,

Asteroid 2012 DA14 will touch the Earth

15 February 2012 DA14 small asteroid will pass so close to Earth that will be inside the ring of Geostationary weather satellites and communications satellites. NASA claims that the observations that are exactly expect the trajectory of near-Earth objects and the probability of collision exists. But the unique opportunity to study the asteroid.
