Is there life after death? This is one of those questions we all ask ourselves. And regarding the stars, astronomers today provide an answer. Some of them, at least, continue to send us signs of life even after their death!

regularly, astronomersastronomers Capture the explosions that occur almost everywhere in our universe. Sometimes billions of light years away from our Earth. Quite diverse eruptions that they manage to classify according to their characteristics. and what they call « Bright Bright Blue Optical Transient » (LFBOT), understand, the “Fast bright blue optical light transient” Are among these. Surprisingly bright explosions – colored blue, which indicates the heat released by the event – ​​and brief – they appear and fade away in a few days, while supernovae, for example, take several weeks to fade, Even takes several months – which still remains very mysterious to eyeseyes astronomer

This is the flattest explosion ever seen in the universe!

Researchers from Cornell University (United States) report in the journal Nature, which he discovered while studying one of these fast blue optical light transients. Which they officially call AT2022tsd, but which they nickname ” Tasmanian Devil “, of lightninglightning Lasting only a few minutes and as powerful as the initial eruption, but which came 100 days later.

absolutely unexpected flash of light

“We had never seen it anywhere”, comments Anna Ho, professor of astronomy at Cornell University. That’s why the researchers immediately called on colleagues for help, and asked about fifteen telescopes around the world to provide them with additional data on the phenomenon.

Astronomers were eventually able to confirm at least 14 GlowGlow Irregular illumination over a period of 120 days. “Probably only a fraction of the totalLoves Anna Ho. And surprisingly, instead of gradually fading as one might expect, the source brightened again for a short time. Even more. Even more. , All this makes this fast blue optical light momentary a bit strange and ForeignerForeigner Researchers had already imagined.

Stars have life even after death

The Cornell University team now believes that the driving force behind this strange activity may be none other than a stellar corpse. Black hole or neutron star. But the exact procedures remain to be confirmed. Nevertheless, these observations may provide new information on the stellar life cycle. To some extent, observing LFBOT was like observing a star’s passage not from life to death, but from life to life after death…

“Because these stars are not dead yet. “They remain active and send us signals that we know how to detect.”, Anna Ho specifies. There is reason to hope that studying these newly discovered flashes will help astronomers uncover some of the mysteries of our universe. Such as how the properties of stars can help predict how they will die and what type of corpse they will produce. Rapid rotation or a strong magnetic field are probably key elements in the appearance of LFBOT. However, it is entirely possible that these transients do not arise from a supernovasupernova traditional, but rather an explosion generated by FusionFusion with a star black holeblack hole,
