NASA's Deep Space Research Galaxy Evolution Explorer (GALEX) has discovered new emerging galaxy in relative proximity to the solar system. This was reported in a press release issued Tuesday by the official website of the mission.

More than 30 of the thousands of new solar systems detected the device at a distance of 2 to 4 billion light-years from Earth, several times brighter than the Milky Way, which is a sign of their active form. The young "ultra" of galaxies is a hundred million to one billion years old (for comparison, the Milky Way was formed about 10 billion years ago).

This suggests that the universe is still being actively developed, scientists said. Previously it was thought that the formation of new galaxies in the nearby regions of the universe (with the exception of their merger) stopped. Young galaxies, open still, located about 11 billion light-years away, on the outskirts of the universe.

The head of the project GALEX Tim Heckman (Tim Heckman) compared with the discovery of dinosaur discovery on your own back yard, reports MSNBC. According to him, scientists can now recover more detailed history of the origins and evolution of galaxies.

GALEX was launched by NASA in April 2003. The main tool it is a 50-inch ultra-violet telescope, which makes wide-angle satellite imagery. The purpose designed for the 28 months of the mission is to obtain information about the stars of distant galaxies that emit a significant amount of energy in the ultraviolet range, and the study of history and the chemical evolution of stellar systems.
