They find one of the oldest stars in the universe

Astronomers detect one of the oldest stars in the universe

UNITED STATES.

With just over 13.5 billion years, the star baptized as 2MASS J18082002-5104378 B, is a true relic of stars.

This is not the first star so old to have been created immediately after the Big Bangbut the only one close enough to us to really study it.

Scientists claim that the star's body only accounts for about 10% of the sun's mass, he has therefore not been detected for a long time while he was in the milky way.

One thinks that The star was formed very early in the life of the universe when there were no metals.

All the investigations, a few years ago, indicated that the first stars would have already died long ago, after burning their fuel reserves and exploding.

However, In recent years, stars "extremely poor metals" have been discovered, which are among the oldest known.

This object is the second poorest in metals after the red giant HE 1523-0901, known as the "galactic fossil" and considered at the beginning of this century as the oldest star of the Milky Way.

The experts they place the "new" star near the flammability limit of hydrogenwhich means that with a lower mass, the ignition of the first chemical element would not have occurred.

This discovery is an important advance to understand how the universe was in its infancy.
