Stars, like planets, are made of different layers. Of course, the technology available today does not allow us to fly into such an object to learn about its exact construction. However, a lot of information about the interior of the star was provided by a huge supernova, which astronomers observed a few years ago.
Superna SN2021YFJ revealed the interior of the star
Observing supernova is very difficult, but in 2021 astronomers were very lucky. They managed to see A powerful explosion of the SN2021YFJ, which occurred 2.2 billion light from us. It was an unusual opportunity for research and managed to see something that shed light on the interior of the star.
Scientists noticed there during observation Silicon, sulfur and argon – elements that were previously not seen in exploding stars. As the astrophysicist Steve Schulze from the Northwestern University in the United States noted, it proof of the existence of concentric coatings of various elementswhich create interiors of massive stars. So far remaining only in theory.
This event literally looks like something that no one has ever seen before. This is the first time we see a star that was practically exposed to CNA
“It shows us how the stars are built and proves that the stars can lose a lot of matter before they explode. Not only can they lose their most external layers, but they can be completely exposed to the bottom, and yet they cause a dazzling explosion, which we can observe from very, very far distances” – adds Steve Schulze.
The sun will also explode someday
Our sun is no exception. He is currently a star in the prime of a century, but in a few billion years he will start to swell. To the extent that the outer coatings can even reach the orbit of Mars. Sometimes an explosion and layers will be thrown into space. A small white dwarf will remain after the star of the solar system.
Of course, humanity will probably not wait at the moment or leave the solar system. As a result of such changes, the earth will cease to exist.
