Earendel is the most distant star in space and time, discovered by the Hubbel space telescope in 2022. There is latest research that warns that Earendel is not a star, nor a binary system as was believed at one time, but that it could be an entire star cluster. Until now, it was believed that this was the oldest star in the universe.
If it is confirmed that it is a star cluster, it will be a lot of stars, not one, but a lot, Earendel or the star cluster was formed just 900 million years after the Big Bang, when the universe was only 7% of its current age, this study that I am talking about was published on July 13 in the bulletin of the American Astronomical Society, Earendel is located in the dawn arc galaxy 12.9 billion light years away. of us.
It was discovered thanks to a phenomenon known as gravitational lensing, a phenomenon predicted by Albert Einstein's theory of relativity. In this phenomenon, massive objects bend the light that passes around them and amplify it, amplifying the image of very distant objects and also in a beastly shape.
In this case because there is a cluster of galaxies around that area and they distort the fabric of space-time creating that gravitational lens, it is not only the light, it is not like the lens, although it is called a gravitational lens, but it is not like our magnifying glasses, it amplifies everything, all types of radiation, that means that if there were radio emissions it would also amplify them.
Arendel now seems to be a group of stars barely 900 million years old and they would practically be made exclusively of hydrogen and some helium, there would be almost no other elements because for other elements to exist they have to be produced within the stars and then that star has to explode, normally it is within massive stars, but there could be because massive stars live for a very short time, 10 to 20 million years and end up exploding like a supernova and expelling materials such as iron, calcium, oxygen, everything. what they have built within them by the universe.
And these materials are important because planets can be created with them, so it is difficult for these incredibly old stars to have planets, but perhaps, there is some possibility that planets do have them and if they did, they would be among the oldest in the universe, planets with 12.9 billion years of evolution.
