Astronomers amazing and constantly make breakthroughs that show us how exciting and booming place is impenetrable abyss of the universe.

This time, researchers from the University of Sydney have made the most terrifying observation of the stars. This refers to the stars of Wolf-Rayet star. These are massive stars in the last stable phase of their lives. Only time separates them from the explosion and becoming a supernova.

Astronomers have discovered a pair of stars that were named Apep. The system is 8000 years from the Earth, and the objects themselves have a weight of 10 to 15 times that of the sun and at the same time is until 100,000 times since it lighter. The temperature at the surface reaches 25,000 degrees Celsius, is 10 time more than our daily star.

Apep emit large amounts of dust. You can even say boldly that they are bathed in it. Published on the graphics we can see how it looks in reality this system. I must admit that very spectacular. It is worth noting that the gas and dust emitted by the stars took the spiral structure and is thrown into space at great speed 12 million km / h.

Why Wolf-Rayet stars are so frightening? Not only because of the spectacular view of their imminent death, but also due to the fact that their remains turn into powerful neutron stars or black holes that will devour the surrounding objects. But it is not everything. In the universe we found them very little, and such systems as we know only a dozen Apep.

Tandems Wolf-Rayet stars are also dangerous because of their rapid rotation around its axis. At the time of the explosion as a supernova, it will automatically giant burst of gamma radiation, which can destroy all kinds of life on subjects that are even as far as the Earth. Fortunately, the axis of rotation Apep is not directed toward our planet, so we can be confident.

Interestingly, astronomers from the University of Chicago recently developed a coherent and complete hypothesis explaining the formation of the solar system. Until now, the world of astronomy, he believed that he was born with the emergence of a supernova. However, according to the hypothesis published in the pages of the journal Astrophysical Journal, it could arise rozwiewanych blistered winds around a giant Wolf-Rayet star.

Prevailing in the interior a high temperature is a great factor for production of various elements. They are blown across by the intense winds Scientists believe that they are the ones pushing apart the dense matter, forming larger aggregates in the form of bubbles, which could be born sun, and later the entire planetary system.
