According to the data sent to earth orbiting space telescope GALEX, astronomers have made the image of the Veil nebula in the ultraviolet range. The Veil nebula (W78, Sharpless 103), which is also known as the Loop nebula or nebula Fishing net, is a diffuse nebula in the constellation of Cygnus. Was opened on 5 September 1784 by astronomer William Herschel. Previously, astronomers believed that this huge and relatively faint supernova remnant that exploded about 5,000 to 8,000 years ago, is at a distance of about 2500 light years from Earth, however, studies that fulfilled the space telescope “Hubble”, showed that the nebula is much closer – at a distance of 1470 light years. However, it extends for a distance of about 90 light-years, taking in the sky region of 3 degrees. Astronomers have smashed the nebula into four parts: separation – nebula “witch’s broom” (NGC 6960). South-West side of the Pickering’s Triangle (NGC 6979), East side (NGC 6992), which represents the fibrous structure of the nebula and the North side (NGC 6995).
Astronomers have discovered in the nearby galaxy M95 supernova. The discovery was made on March 16, 2014, when astronomers, both professionals and Amateurs, noted a bright spot on the outskirts of a spiral galaxy with a jumper M95 (NGC 3351), which is at a distance of 38 million light-years away in the constellation of Leo.

The origin of the solar system
The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .
Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.
Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.
The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available. Continue reading
Comet Churyumov-Gerasimenko are two comets stuck together
The researchers of the mission “Rosetta” said the comet 67/P Churyumov-Gerasimenko acquired its form as a result of collision at a low speed of two different comets in the early development of the Solar system.
A team of researchers under the leadership of astrophysics Massironi Matteo (Matteo Massironi) from the University of Padova (Italy) look at the Photos of the comet 67P/Churyumov-Gerasimenko, taken in high resolution in the period between 6 August 2014 and 17 March 2015, it Became evident that the comet was formed as a result of collision of two different bodies, flying at low speed. The results of the ESA study says .
Recall, the first images of the comet from close range, the probe “Rosetta” in July 2014 showed that the object consists of two “blocks” of different sizes. and resembles the shape of a rubber duck. Scientists examined two hypotheses: the first is that the cosmic body had acquired such an unusual form as a result of a collision between two comets, and another stated that the “neck” of the comet formed in the process of natural erosion of rocks that make up the object. Now, however, the researchers got convincing evidence in favor of the first. Continue reading
