An event that was already considered past, returns to surprise the scientific community.
Science has a thousand and one ways of showing us how amazing the universe around us can be. From Urban Tecno we have already shown you a telescope like the NuSTAR, which is capable of ‘x-rays’ to outer space and detect possible black holes. Now it looks like a old event between one of these mysteries of the cosmos and a star has a second part.
Even if you are a black hole, you will have to burp after consuming stars
It was in October 2018 when a group of astronomers detected a star being swallowed by a black hole 20 million times larger than our Sun and 665 million light years away. The eventknown in astronomical jargon as tidal disruption eventwas named as AT2018hyzbut after the starlight was consumed months later, it was stored in the forgot. And this has been the case until recently, according to the study published in The Astrophysical Journal, since we have just witnessed the reactivation of said black hole and of one reaction that few expected.
A light seems to come from said hole and It is not because none has been swallowed again star. yvette cedeslead author of the study that we showed you earlier, has stated on The Harvard Gazette website that:
It has caught us completely by surprise. No one had seen anything like this before.
The conclusion What the team of scientists responsible for analyzing such a strange event has revealed is that the black hole it seems to be ejecting material at half the speed of light, although they still do not explain how it has taken so long to do so. However, it seems that this freak will serve many researchers understand in depth the behavior of black holes and how they feed. That’s why the comparison between the recently observed event and burping after a meal seems logical, according to Yvette.
Is expulsion of material was discovered while the team reviewed past tidal disruption events. Using data obtained from Very Large Array radio astronomical observatory in New Mexico, discovering that in June 2021 this black hole had been reactivated. The light that a black hole emits when it engulfs a star usually revives after a while, but never in a space as long as the one shown in this phenomenon. Edo Bergerprofessor of astronomy at Harvard University, it states that:
It is the first time that we have witnessed such a long interval between consumption and expulsion. The next step is to explore if this really happens on a regular basis or if we haven’t been keeping an eye on tidal disruption events long enough in their evolution.
