To Jupiter research probe Juno is directed

With the cosmodrome located on cape Canaveral, and to Jupiter started interplanetary research probe Juno. This research probe becomes the space vehicle first for last fifteen years which will be directed on studying of this gas giant. Mission is estimated in the cost, equal 1,1 billion dollars. For this purpose that the probe would reach Jupiter, to be necessary for it four years. However it is necessary to notice that yakt that at the start, the probe will go not at once to the purpose of the mission, and in 2013 it again will return to the Earth, having flown about it, for fulfillment of gravitational maneuver and reception of additional acceleration.

Research probe Dawn has reached an asteroid of "Vesta"

To one of the largest asteroids which orbit lies between an orbit of Mars and Jupiter. The asteroid of Vesta is the asteroid second for the size which is in the Main asteroid belt. For research of this space body, in 2007, to it towards, space research probe Dawn has been sent. In July of current year, the research probe has orbited an asteroid, in September it has come nearer to a surface of Vesty on distance in 600 kilometres, and by November, will be at height in 200 kilometres from an asteroid surface. The primary goal which has been assigned to a research probe, fulfillment of framing of a surface of an asteroid which outwardly, bears a strong resemblance to the Moon surface enough.
Often enough, Vesta is perceived not as a large asteroid, and as very small planet. It is possible to explain it to that Vesta has a number of features and properties with which other planets of Solar system, such as Venus, Merkury, Mars or the Earth possess. However because of the small size and consequently also weights, Vesta cannot keep atmosphere round itself.

Usual pair of dead stars is found out not

In constellation of the Maiden, scientists find out symbolical enough pair of stars. The friend round the friend one not born star and a dense space corpse another rotate. Two these stars which and not managed to turn to high-grade space objects, form strange enough pair. One of stars is the brown dwarf, the second the white dwarf. Both these stars, form strange enough pair, rotating thus round one general centre of weights. To find out them it was possible thanks to a telescope of the Hawaiian observatory.
Both found out dwarfs belong to enough rare group of space objects, and the similar neighbourhood of white and brown dwarfs in general do the found out group unique. The similar neighbourhood extremely seldom also represents on true the present find for astronomers.

Double stars can quite promote greens development on planets

Among a large quantity of the stars known to scientists of the Earth, only small part can become a haven for this purpose that on a planet about them life would arise. However now, before scientists there was a question, whether life on a planet which exists in double star system can arise.
Two sun ascending over horizon of a planet – a favourite picture for all fantastic films. However the similar show can be observed from surface of some planets which are found out by scientists outside of Solar system. Already now scientists try to foresee, what vegetation on similar planets would be, considering the fact of that it would receive light at once from two sun.
For the scientist star systems with two sun and planets with which those shine are already known. And now every possible hypotheses concerning that are under construction, than the similar systems having two sun, differ from what have only one.
