Unprecedented discovery of the twin brother of the sun in the light of 184 | News from El Salvador




Astronomers have long sought the sisters of the Sun, born in the same dust and gas cloud of our star.

It is said to be very similar to the sun, not only the sister of the scientists, but also the twin.

An international team of astronomers found a star resembling a carbon copy.

It has a very similar and almost identical chemical composition to the same temperature and brightness as about 4.500 million years.

Twin stars, called HD 186302 He is 184 light years away and will allow scientists to investigate the rise of the sun, which will continue to be a mystery.

In Since there is not much information about the history of the sun, the examination of these sister stars can help us to understand where and in what conditions the sun is formed in the galaxy. “ Vardan Adibekyan astronomical Institute of Astrophysics and Astronautics.

Star Cradle

Astronomers have long sought the sisters of the sun, They are formed in the same cloud of gas and dust. our .

So far, there have been very few nominees to become sun sisters.

This star cluster could have had many sisters in the sun, but it was very difficult to identify them.

It is known that thousands of stars are formed in these cribs or star nurseries, but it is very difficult to find them when they are dispersed in the Milky Way.

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

In cooperation with Patrick de Laverny and Alejandra Recio Blanco, we have taken a sample of 230,000 spectra from the Observatorio de la Costa Azul, an AMBRE project (an initiative created by the European Southern Observatory and the Costa Azul Observatory).

Scientists also used spectral data in a very large star pattern obtained by the European satellite Gaia.

"World 2.0"

One of the biggest questions that astronomers will try to answer is whether a planet around HD 186302 can support life.

"Some theoretical calculations show that life is unlikely to be ignored the world other planets or exoplanetary systems During the last intense bombardment period, "Adibekyan said.

The intense bombing belonged to about 4,000 million years ago when the bodies of the Solar System were hit by large asteroids.

The possibility of detecting life signs on an outer planet of the Sun twin reveals Adibekian.

"If we are lucky and our sunshine has a planet and the planet is rocky, in a habitable region, and finally, if this planet is contaminated by the seeds of life in the World, then the dream is what we can imagine: a Sun 2.0 or a Sun 2.0 orbit."
