Astrophysics recorded and tracked the birth of positrons in the Sun upper atmosphere. This supervision will help to understand why there is no anti-matter in the Universe. Scientists presented the opening at conference of the American astronomical community. It is considered that during the first instants after the Big Bang there was an equal quantity of a matter and antimatter particles. Nevertheless, today the world is filled with a usual matter. This fact is a physical riddle as matter and antimatter particles had to destroy each other while they appeared in future Universe. Therefore there is a question — where was gone the anti-matter and why there is a Universe. Gregory Fleishman from Institute of technology of New Jersey (USA) and two co-researchers suggest using the Sun for search of the answer to this question. According to astrophysicists, on the Sun and other stars there are all conditions for formation of antimatter particles.
On Thursday from air base Vandenberg in California was started the rocket Pegasus XL with specialized solar observatory of IRIS device onboard. The satellite intended for research of processes in the atmosphere of the Sun, is successfully put to settlement orbit. The IRIS device is calculated on two years of active work. In the next month it will pass flight tests then scientists will start to work. The ultra-violet telescope established onboard with a 20-centimetric mirror will allow in combination with the new spectrograph and the camera to receive earlier inaccessible information on the Sun atmosphere. The satellite is made counting upon detailed research of the photosphere, the chromospheres and so-called transitional layer.
In December 2011 the comet Lovejoy (C/2011 W3), endured extremely close rapprochement with the Sun. The comet helped scientists to probe structures of a magnetic field in the closest vicinities of a star where no spacecrafts can get. Comet Lovejoy C/2011 W3 was found by the Australian astronomer Terry Lovejoy on November 27, 2011. Calculations showed that on the night of December 16 the comet will fly by at the minimum distance from the Sun — only in 140 thousand kilometers from a star surface. It is more than 100 times shorter than a distance between the Sun and Mercury, and is twice less, than distance from the Moon to Earth. Scientists were sure, that the comet completely will evaporate even before perihelion passing. However the comet safely rounded the Sun and left on the other hand that became sensation for astronomers.
The star, which is close to Earth, grows in constellation Hydra, actively “eating” gas from the protoplanetary disk, in the same way could develop the Sun. TW of the constellation Hydra — being at distance from our planet a star age of 10 million years became about 180 light years object of research of scientists. The star weight is slightly less than Sun and have own protoplanetary disk. According to astronomers studying TW of the constellation Hydra, they will be able to understand that happened to our Sun when it was “kid”. In the work scientists used the data obtained by orbital x-ray observatory of “Chandr” and land telescopes. It became clear that for the growth of star of the constellation Hydra “exhausts” from a protoplanetary disk gas. Then the gas moves on lines of a magnetic field to star poles.
The Brazilian astronomers reported about opening of the new twin of our solar system. The Brazilian scientists from Rio Grande do Norte University officially reported about opening of almost identical twin of our solar system. The star similar to our Sun is called as CoRot Sol 1. Now our Sun has any more one twin. Gradually scientific opens more and more stars similar to the central star of our Solar System. The solar twin received CoRot Sol 1 designation as it was open with help of the space Corot satellite started on 2006. The star of CoRot Sol 1 is today the most remote Twin of our Sun. Just as our Sun, its’ remote twin is the yellow dwarf. This SP of small stars of the main sequence having weight from 0,8 up to 1,2 weight of the Sun and temperature of a surface 5000-6000 K. According to the name, by results of a photo material they have yellow color; though subjectively their color is perceived by the person as the purest white (hotter stars will be perceived by the person as bluish or blue). The main source of their energy is thermonuclear synthesis of helium from hydrogen.
At the end of March we will say goodbye to a comet C/2011 L4 forever. On March 10 the comet C2011 L4 approaches to the Sun as much as possible. The astronomers from astronomical observatory McDonald, the comet C/2011 L4 Panstarrs has vary long elliptic orbit. For the full passing with the orbit the comet needs approximately 100 million years. After March the comet C/2011 L4 Panstarrs will leave vicinities of the Earth and the Sun. On March 10, the comet C/2011 L4 Panstarrs will fly maximally close to the Sun. The distance between the comet and the Sun will be 45 milion kilometers. As the comet is very bright, it is possible to watch it with the naked eye. On the March 5 the comet approached to our planet, and the distance between the comet and the Earth was 162 million kilometers.
HD 10056 is the young star which is near to the Earth about 335 light years. The astronomers, who are studying the HD 10056 star, think, that they are witnessing the birth of a giant from gas. This giant will be three times larger than Jupiter. If this discovery is confirmed, it will change the understanding of people, regarding the comparing the theories of scientists, with direct observations of new planets.
NASA’s Cassini spacecraft has delivered view of Saturn, taken while the spacecraft was in Saturn’s shadow. The cameras were turned toward Saturn and the sun so that the planet and rings are backlit. This special, very-high-phase viewing geometry lets scientists study ring and atmosphere phenomena not easily seen at a lower phase. Since images like this can only be taken while the sun is behind the planet, this beautiful view is all the more precious for its rarity. The last time Cassini captured a view like this was in Sept. 2006, when it captured a mosaic processed to look like natural color.
Apophis previously known as 2004 MN4, a member of the Aten group of near-Earth asteroids which had been estimated by NASA as having a 1 in 5500 chance of striking the Earth in 2029. Concealing the energy of 65,000 atomic bombs asteroid Apophis with a mass of 50 million tonnes and a diameter of 320 meters will cross the orbit of the moon and rush to the Earth with a speed of 45 thousand miles per hour. In a collision of Apophis might do unseen troubles.
