The huge discovery of the twinbridges of # 39; the sun at 184 light years Technology and science | Science


It is similar to the sun scientists say it's not just his sister, but his twin.

An international team of astronomers discovered a star that looks like a galaxy of ours.

It has the same temperature and luminosity, a chemical composition very similar and almost the same age, or 4.500 million years.

The twins, called HD 186302, is 184 light-years' feet and scientists will investigate the birthplace of the study, which remains a mystery.

"If there is not much information about the past of age, we can study these sister stars where we can get in the galaxy and under what conditions the sun is formed," he said in a statement. Vardan Adibekyan, astronomer of the Institute for Astrophysics and Space Sciences of Portugal, which conducted the study.

Astronomers have long sought after sister of the sun, which is stars They are in the same cloud of gas and dust as ours.

In addition, many candidates for sun-sirens have been identified.

It is known that thousands of stars were formed in those sleeping or starving girls, but they were thrown in with the passage of ' The Milky Way, so it's very hard to find them.

Adibekyan and his colleagues used a successful method in their research.

"With the collaboration of Patrick de Laverny and Alejandra Recio Blanco, of the Costa Azul Observatory, we had a 230,000 spectrum of the AMBRE project (an initiative that was created by the European Southern Observatory and the Costa Azul Observatory).

The scientists also used spectral data in a very big problem of stars obtained by the European satellite Gaia.

— "Earth 2.0" —

One of the great questions that astronomers try to answer is whether a planet to have HD 186302 had life.

"Show some theoretical calculations that a non-negative is likely to allow the life of Earth to expand to other planets or exponential systems In & # 39; the period of & # 39; The latest intense bombardment was Adibekyan.

The intense bombardment was a period of 4,000 million years ago when the bodies of the solar system were hit by large asteroids.

The ability to influence the signs of life in an expansion of sun-twine Adibekyan.

"If we are fortunate and our sun-sister has a planet and the planet is rocky, it's in motion of the zone, and ultimately, if this planet is contaminated by the seed of life on earth, then we can dream something: an earth 2.0, orbiting in Sun 2.0 ".
