This time, scientists from the University of Sydney made observations of the most terrifying stars. We are talking about Wolf-Rayet stars. They are massive stars in the last stable phase of their lives. It is only moments away from an explosion and becoming a supernova.
Astronomers have discovered a pair of stars that have been named Apep. The system is located 8,000 years from Earth, and the objects themselves have a mass 10 to 15 times greater than the Sun and are 100,000 times brighter than the Sun. The temperature on their surface reaches 25,000 degrees Celsius, which is 10 times higher than on our day star.
Apep emit huge amounts of dust. You can even say that they are bathed in it. In the published graphics, we can see what this layout looks like in reality. I must admit that it is very spectacular. It is worth adding here that the dust and gas emitted by the stars took on a spiral structure and is ejected into space at a huge speed of 12 million km / h.
Why are Wolf-Rayet stars so scary? Not only because of the spectacular picture of their top web tutorials death, but also due to the fact that their remains will turn into powerful neutron stars or black holes that will begin to devour surrounding objects. But it is not everything. We have discovered very few of them in the universe, and there are only a dozen or so systems like Apep.
Wolf-Rayet tandems are also dangerous because of their rapid rotation around their axis. When it explodes as a supernova, a gigantic burst of gamma rays will automatically occur and can destroy all life on objects as far away as Earth. Fortunately, Apep's axis of rotation is not directed towards our planet, so we can rest assured.
Interestingly, astronomers from the University of Chicago recently developed a very consistent and complete hypothesis explaining the formation of the solar system. Until now, the world of astronomy believed that it was born as a result of the appearance of a supernova. However, according to a hypothesis published in the Astrophysical Journal, it could have arisen in wind-blown bubbles around the giant Wolf-Rayet star.
The high temperature inside them is an ideal factor for the production of various chemical elements. They are blown all over the space by intense winds. Scientists believe that they push up dense matter, creating larger clusters in the form of bubbles, in which the Sun could be born, and later the entire planetary system.
