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.

"Curiosity" began to drill the surface of Mars

At the first time "Curiosity" tried his drill on the surface of Mars. According to BBC News, the robot has continually struck by a brown rock on the surface of the Gale Crater.

On the rover obtained images show traces of the chisel. Until now, the surface of the Red Planet's drill did not try.

Light from the dark cloud

ESO shows a dark cloud in which new stars are formed straight, while a collection of bright stars, who have left their dusty nursery already.

While on the left side of the new recording sees a dark, elongated structure resembling a cloud of smoke on the right side, a small group of bright stars lit the scene. At first glance, the two parts of the image not to be contradictory, but in reality they are closely linked. 

Fire in the dark clouds

The Atacama Pathfinder Experiment (APEX) in Chile offers a beautiful view of clouds of cosmic dust in the group Orion. In observable light, this dense interstellar cloud appears dark and solid. The LABOCA camera on APEX, however, can detect the heat radiation emitted by dust and so do the hideouts of the just emerging star locate. One of these dark clouds is not what it seems.

Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. In visible light, the dust appears dark and opaque so that it hides the stars behind.

The largest-ever solar boat

American scientist’s Agency NASA makes known plans to launch in 2014, the year of the largest in the history of the solar sail. Sail area of 1.2 thousand square meters. The name of this project served as a famous story by Arthur C. Clarke of 1964 Sun jammier, which refers to the regatta "solar boat". Side length of the sail is almost 38 meters high, and it will produce L" Grade - the company that in the late twentieth century sent experimental" inflatable "antenna on the ISS. 

Make stars are born

Astronomers have calculated that the birth of planets around young stars can occur even at a later stage than previously considered. In the study of the properties of star TW Hydra found strong evidence. This star is at a distance of 176 light-years from Earth, refers to the spectral type K8 and attracts the surrounding gas and dust astronomers drive. A few years ago, close to the TW Hydra was discovered planet, which weighs slightly larger than Jupiter.
