NEW PLANET

Our Solar system keeps many of surprises. And one of them, a new planet, which has just been revealed by a group of astronomers. It is a questionof an object of between 500 and 1. 000km in diameter and that one finds three times further of the Sun that Pluto. It is the most distant body discovered till now inside our own planetary system. Inexpectation of a name, it has been designated as V774104.
It will be necessary to have another finished year of investigation to determine with accuracy the orbit of the new planet and its other characteristics.

PLANETARY SEQUESTRATION

The Solar system continues the enormous mass of the Sun the length and breadth ofthe space. But  between its planets surrounded by an enormous skin of rocks and asteroids that is called an Oort cloud, it highlights the threatening presence of anenormous gaseous planet: Jupiter.

It has been suggested that Jupiter could be the person in charge of the expulsion of another planet of   the Solar system when the formation was formed, 4. 000 millionyears ago.

Could happen is that Jupiter was approaching so much another planet that was accelerating it up to   the point of  being liberated of the gravitational attraction ofthe Sun.

IS THERE WATER IN MARS?

A group of scientists of the NASA assures to have evidences of which there are water courses in Mars.Specifically they have studied the craters Palikir, Haley and Horowivh placed in the south hemisphere of the planet.

The exploration has been done by CRISM, an espectómetro of the probe MRO that serves to identify minerals. 

To simple sight, key sound join dark spots that can be seen in the most warm epoch (with temperatures of 23 grades under zero) and that disappear at the coldest station. The CRISM has detected from these images the presence of hydrated salt. 

The explanation, according to the scientists, is that the Red Planet has water courses that stop flowing when the climate cools down (the salt helps to the water to stay liquid up to a temperature of approximately 70 grades under zero).These courses would be for the  mos t part tubes, although a part would go out to the surface and that would explain some of the ruts in the Martian relief that have been observed in this one and other missions.
