Scientists have observed a supernova explosion

An international team of researchers, including domestic, studied the radiation from the supernova explosion. The results of own researches of the authors published in the journal Nature.

Eugene Churazov together with the staff examined data from the INTEGRAL satellite of the European space Agency, acquired between 50 and 100 days after the explosion of a supernova SN 2014J. Bright radiation from the explosion were observed for 3 weeks, then it exponentially dozed. On its own peak radiation in the 4 billion times the light output of the Sun.

Researchers have demonstrated that radioactive isotopes of Nickel-56 (with a half-life of 6.1 day), emerged in the 1st second after the explosion of a supernova and collapsed on the isotope cobalt-56 (with a half-life of 77 days), and further, the stable isotope iron-56, which has led to the emergence of x-ray radiation, which was observed by the experts. However, scientists do not exclude that this radiation could not arise in the investigation of nuclear reactions and, as a result of the conflict 2 white dwarfs.

Supernova SN 2014J is located in the galaxy M 82 (Cigar) and it is considered the closest to the Earth from the object type found in the past 40 years. Spiral galaxy Cigar is located in the constellation URSA major at a distance of 12 million light years from the Sun.

Herself SN 2014J is of type la supernovae and was opened in early January 2014. It inadvertently noted astronomer of the University's Institute of London. View la brings together a group of supernova that formed after the thermonuclear explosion of white dwarfs.

White dwarfs are not actually occurring thermonuclear reaction
