Astronomers from John Morse University and Montpellier Liverpool have received a warning about the end of a star’s life to a supernova (red supergiant) that Monthly Journal of the Royal Astronomical Society of Great Britain It’s been published.
In this new study, researchers have found massive stars in the last phase of their life, which have a mass of about 8 to 20 times that of the Sun, which is called this phase of star death. red supergiant have called At this stage, just before they die, they are about a hundred times fainter in visible light. These light changes are due to the accumulation of material around the star, which darkens the light.

How does a red supergiant explode into a supernova at the moment of its death?
Until now, it is not clear to us how long this matter sticks to the star. Now, for the first time, researchers have been able to simulate what the red supergiant might have looked like pre-explosion. What do you think the resulting image was? Butterfly cocoons!
Archives of old telescopes have revealed images of existing stars that were on the verge of exploding, and these images were taken before these explosions. The stars appeared in these images were in a normal state, meaning that they are still in the theoretical phase cocoon belt have not been These suggestions tell us that the cocoon was formed less than a year ago and that the processing was very rapid. Lead author Benjamin Davies of the University of Mauritius says:
“The dense matter almost completely makes the star about 100 times fainter in the dark visible spectrum. All this means is that the star is just one day away from exploding, and you probably wouldn’t want to be there when that happens!”
“Until now, we were only able to observe the details of the death of supernovae about an hour before the event. But today, with the early warning system, we are able to observe them immediately, and point the best telescopes in the world towards new stars and witness their collapse literally before our eyes!
