UNITED STATES (VOP TODAY NEWS) – The star, whose age reaches 13.5 billion years, that is, comparable to the age of the Universe, was discovered by astronomers from Johns Hopkins University in the US.
It has a mass constituting only about 14% of the mass of the Sun, is part of the binary star system and received the designation 2MASS J18082002-5104378 B in the astronomical catalog.
“This star is probably one of 10 million,” astronomer Kevin Schlaufman’s Internet portal leads Space.com. “Her study will allow us to learn a lot about the very first generation of stars in the Universe.”
The first stars formed after the Big Bang, according to current scientific concepts, consisted of the lightest elements — hydrogen, helium, and a small amount of lithium. Now astronomers know about 30 very old stars, which include few heavy elements.
“If our assumptions are correct, then there may be stars with low mass and preserving the structure from the time of the Big Bang,” Kevin Schlaufman said. “We have not yet found a similar object in our Galaxy, but such an object may exist.”
The diameter of the spiral Milky Way, in which the solar system is located, is estimated at 100-200 thousand light years, and there are 200 to 400 billion stars in it.
According to one of the hypotheses, Space.com reports that in 4 billion years our Galaxy will collide with the Andromeda Galaxy.
