The "oldest star" of the universe observed by astronomers - TF1

The oldest known star, which could help to better understand the origins of the universe, was recently discovered by Australian astronomers. After eleven years of work, a team from the Research School of Astronomy and Astrophysics at the Australian National University was able to observe the chemical fingerprint of the “first star”, which was formed shortly after the Big Bang, currently 13.7 billion years.

“This gives us a glimpse of our fundamental place in the universe. What we observe is the origin of all the materials we need to live,” said Dr. Stefan Keller, head of research. The star in question is 6000 light years from Earth, which is relatively close to the astronomical scale. She is one of 60 million stars phortographiés SkyMapper the telescope during its first year of operation.

“This is the first time we formally able to say that we are in the presence of data from the first generation of stars. Now we can put this piece in its place in the puzzle, “continued Dr. Keller, whose research is published in the latest edition of the journal Nature.
