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.

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
Why Just the ninth planet in the Solar system, according to the International astronomical Union (IAU), there are eight planets. Pluto the IAU decision in 2006 is no longer considered a planet by going to the class of dwarf planets because it is not dominant in its space orbit. According to scientists, the Solar system may be over two thousand dwarf planets. However, the definition of a planet as a dwarf is still a matter of controversy. In particular, a crucial role may play the size of a celestial body.
Therefore, to say that discovered ninth planet in the Solar system very early.”
The scientist reminded that beyond the orbit of distant planets in the Solar system has many objects that are studied by astronomers. Among them was discovered a new heavenly body, which claims the title of planet in the Solar system.
According to the authors, it is a gas giant with a mass of 5-10 times the mass of the Earth. This planet supposedly moves in an elliptical orbit, making a complete revolution around the Sun for 10-20 thousand years. According to the calculations of astronomers to confirm the planet’s existence by observation through the telescope, will take several years. Continue reading
