Astronomers have found closest to our Earth binary system
Astronomers have found the closest to our Earth binary system March 12, 2013
Astronomers are constantly looking for new discoveries in the most remote parts of the universe. Or at least to the extent to which current technology allows them to look. But it also happens that a rather significant discoveries and findings are literally in our “backyard.”
A group of scientists recently found not one, but two stars, a very close to our solar system – only some 6.5 light-years.
The new binary system is the third closest to our Earth, Alpha Centauri, and after star Bernard. WISE 1049-5319 – it was called – consists of two brown (brown) dwarfs. And they (brown dwarfs), as their name implies, are very small and dim light. That is why the system is not found before.
Sometimes referred to as a failed brown dwarf stars. After their formation process is almost identical to the formation of other stars. But the dwarfs have insufficient mass for thermonuclear reactions. Without this process, which literally feeds any star, brown dwarf stars are more like large gas giants than the stars themselves.
However, this is the closest binary star system was discovered already in 1916. The system, which has found satellites NASA WISE (Wide-Field Infrared Survey Explorer), has now become the main goal of scientists to search for potentially suitable for life exoplanets, even despite the fact that the lack of glow dwarfs themselves create additional difficulties in the search.
