Recently group of astronomers made a discovery that may change our vision of universe history. They discover the new galaxy, named CR7, when placed maybe the earliest stars in universe. This discover may help understand how our universe was born, was grow and still developing and thats why it’s so important.

As it turned out, it contains the stars belonging to type III population, similar to the first stars of the universe. Previously, their existence was predicted only in theory. The study accepted for publication in Astrophysical Journal (preprint), and briefly with him can be found in the press release of the European Southern Observatory.

Researchers using the Very Large Telescope, and the Keck Observatory and the telescope “Hubble” spent most extensive at present an overview of distant galaxies. The light from them is so long that astronomers can see them as they were billions of years ago. In the new study, researchers looked at galaxies that formed in the epoch of reionization, after only 800 million years after the Big Bang. A review of astronomers have discovered a number of extremely bright and young galaxies, the brightest of which CR7.
