The brightest Supernova turned out to be a star, torn by a black hole

ASASSN-15lh

Last year, the limits of the Earth reached a light echo of a powerful explosion that exploded the universe, from the epicenter of which we are separated by a giant distance of 3.8 billion light years. The event received the conditional name ASASSN-15lh. Originally there was a version of the appearance of the most striking in the history of astronomical observations of the Supernova. Suffice it to say that its brightness was 50 times higher than that of the entire Milky Way.

However, later with the help of data from the Observatory Las Cumbres, scientists came to the conclusion that the cause of the giant outbreak was something else. According to the new version, a massive star, which was too close to a rotating black hole (also known as a Kerr black hole) literally tore to pieces.

The cause of the mega explosion was the so-called tidal forces, which became known in 1975. However, it was not easy to observe them. As the star approaches the rotating black hole, its powerful gravity activates the colossal tidal forces of the star. In this case, which is quite natural, the near part of it is subjected to a stronger gravitational effect than the others. The resulting differential of force caused a rupture of the star.

And then, according to scientists, the following happened. Fragments of the shattered star before they found themselves inside the black hole began to collide with each other at a tremendous speed. The power of this energy was 570 billion times higher than the intensity of solar flares observed by us from the Earth.
