Scientists first saw how the dying star exploded, and the AP News had a rare opportunity to observe the evolution of the stars.
The supernova, 2021yfj, is located in more than two billion light years from the ground. The outer strata of the collapsed star, which consists of hydrogen and helium, has been separated for a long time, which is not surprising. However, the dense inner layers of the star consisting of silicone and sulfur are also separated during the explosion.
This discovery confirms the hypothesis of how scientists look at the end of the life cycle of large stars: it consists of layers where lighter elements are outside and heavier – closer to the nucleus.
It is still unclear how this star is so small: whether the layers have been thrown with great power in the final stages of their life or whether they are twin stars. Although scientists acknowledge that it would not be easy to repeat such an event, future research can answer this question.
Meanwhile, it was told that Western Japan was told that a large fireball was sweeping, shocked the inhabitants and blinded the observers behind the stars.
