Scientists are like sin, saying that scientists are not just his sister, but his twin.
International astronomers have identified a star similar to our carbon copy.
The same temperature and gloss, chemical composition very similar and nearly the same age, about 4500 million years.
The twin star called the star HD 186302 , 184 light years away and scientists will be able to explore the birthplace of the sun, which remains a mystery.
"Since there is not much information about the past, it can help us to understand where and how the galaxy was created," he said in a statement. Vardan Adibekyan , Astronomy of the Portuguese Astrophysics and Space Science Institute.
Astronomers have long sought out day-to-day sisters – stars they were the same gas and dust a our .
Today, there are fewer sisters in the world.
Thousands of stars are known to have originated in cradles and star nurseries, but it is difficult to pass through time and find the way to Samanjol.
Adibekyan and his colleagues used a complicated method in their research.
"A sample of 230,000 spectrum of AMBRE project (European Southern Observatory and Costa Azul Observatory initiative) was obtained in collaboration with Observatorio de la Costa Azul, Patrick de Laverny and Alejandra Recio Blanco."
Scientists have used the spectral data acquired thanks to the European satellite Gaia for a very large number of stars.
One of the big questions the astronomers are trying to answer is whether the planet around HD 186302 can come into existence.
"Some theoretical reports show that there is a possibility of life impossible It could have extended from Earth to Earth other planets or exotic systems during the latest intense bombing, "said Adigey.
Intensive bombing took place about 4,000 million years ago, when the Sun's bodies were in the form of a large asteroid.
The ability to identify the life-forms of exodus Adiebyan's sunlight.
"If we are happy and your sun has a planet, and if the planet is rocky then it's in a living space and if the planet is polluted with the seeds of the seeds on Earth, then what a dream we have: Earth 2.0, the orbit of the Sun 2.0."
