When stars complete their lives, they are called supernovae. with glorious explosions We know they’re gone. However, this event is very difficult to observe, the probability of catching the last moments of a star in the infinity of space is very low.

Using clustered galaxies, an international team was able to measure three times the bright light emitted by a supernova in deep space. The information from these observations is end of the stars It will also serve to test theories about it

A supernova that even telescopes cannot see

The star itself is located quite far from our planet. At a distance that we cannot see with any telescope, 11.5 billion light years As the last lights of this distant star completed their journey to our planet, it was also a difficult challenge to separate the star’s lights from the lights of all other galaxies.

When he can separate the lights from the star, scientists can see how this celestial body works “live and die” managed to reveal. Unusual twists and shifts in incident light due to gravitational fluctuations managed to reveal the supernova’s existence. This configuration, called the Einstein Transit, revealed information about the star’s life.

Investigated for eight days flares and light changesshowed that the supernova had cooled considerably in a week. This is shown as a development that allows us to predict exactly how stars will turn into supernovae in the future.

According to the researchers, this star was the same as our sun before it exploded. 530 times reached volume. Stars first expand considerably when their fuel runs out, and then quickly collapse towards their own cores. After this collapse, they complete their lives with a gigantic nuclear explosion, a supernova. Thanks to the new observation, this process will be examined in much more detail.

Study, nature was published in the magazine.
