This finding brings evidence to the ideas of scientists who have how great stars look near the end of their lives. The study was published in Nature magazine.
The stars They can live from millions to billion years until they run out of fuel. In this way, the largest mass end with an explosion called Supernova. In the last hours, a group of US scientists, for the first time they observed in history the interior of a dying star while exploding.
Research, published in Nature magazine and Coordinated by Steve Schulzefrom the US Northwestern University, it revealed phenomena that only raised as a hypothesis. “This is the first time we observed a practically stripped star of its foundations“Schulze said. He also added that he showed them how the stars are structured and showed that they can lose a lot of material before exploiting. For their part, Adam Miller, co -author of the study, said:”It was so strange that we thought we were wrong“
This finding Provides evidence To the ideas of the scientists who have how the big stars look near the end of their lives, organized in layers with lighter elements outside and heavier near the nucleus. “Because many of the layers had emerged from this star, this basically confirmed what those layers were“said Anya Nugent, who studies Superovas in the center of Astrophysics Harvard-Smithsonian

Normally, when a massive star exploits, it does so with such violence that its Internal and external layers are completely mixed and messy. This prevents astronomers from knowing how they were structured just before the outbreak.
Explosion of the stars: how the supernovas originate
The stars They are large light gas sphereswhose severity itself pushes them to compact more and more until reaching a density high enough to induce fusion and, therefore, generate heavier elements.
This process continues for millions or billions of years and leads to formation, around stars with masses Between 10 and 100 times higher than the sunconcentric layers of lighter elements abroad and increasingly heavy elements inside.
However, when the balance between fusion energy and collapse gravity, lstar exploits violently. Shortly before this occurs, some stars detach themselves from their external layers of residual hydrogen, which reveals its inner layers of helium or carbon and oxygen.
