A powerful explosion occurred 500 million light-years from Earth

(ORDO NEWS) — Specialists working at Northwestern University in the United States reported that they had found a completely new kind of phenomena in space that relates to transients. These are objects that can change brightness in the process of releasing an impressive amount of energy.

The observed anomaly is called FBOT. It represents blue optical transients, only three of which scientists have encountered before. The phenomenon is a powerful explosion, it can be observed in optical, x-ray and radio beams.

Astronomers have figured out which object caused the explosion. It is located 500 million light years from us, the body is called CSS161010. Scientists noted that the object is similar to the body of AT2018COW, which was observed 06/17/2018 at 195.7 million light years. Then the experts were surprised that the luminosity of the find in just a few days increased to record levels (to the level of supernovae). A strong flash formed, which grew at a speed of 42 thousand km per second.

The new transient was even faster. The formed particles and gas moved at a 55 percent speed of light. Previously, experts believed that only gamma-ray bursts that emit matter with a mass of only 1% of the mass of the Sun are capable of this. The discovered object was able to disperse elements whose weight is 10% of the mass of the star. Scientists have come to the conclusion that FBOT may be the fastest process in outer space.

Perhaps the rarest phenomenon has arisen due to the absorption of the transient by a black hole. It is also worth noting that such observations are relevant only for small galaxies, where no more than 10 million stars (billions of objects in our galaxy) and which contain little metal. Such stars retain mass during their period of existence, and then explode. This explains why FBOT cannot be found in large galactic systems.
