Discovered the most distant galaxy


Recent observations have allowed astronomers to detect the most distant galaxy ever seen by man. The light of this galaxy has traveled to 13.1 billion light years, which makes this galaxy one of the first formed after the Big Bang.

A new galaxy about 30 million light-years beyond the previous record holder - gamma-ray bursts, which lasted for several hours and two hundred million light years further away than the most distant galaxy.

"We are approaching the limit of the observable universe," - said astronomer Michel Trenti of the University of Colorado, who was not involved in the new work. "This is a big breakthrough."

The discovery, published in the journal Nature on 21 October, will help determine what role in the formation of a transparent universe, played the young stars.

A new champion, named UDFy-38135539, was discovered in 2009 by the Hubble Space Telescope photo titled Ultra Deep Field, made with an exposure of more than 11 days. In this photo imprinted over 10,000 galaxies from the very early stage of the universe, some of whom were candidates for the title of the most distant galaxies.

Because light takes a while to move in the universe, telescopes see galaxies as they were billions of years ago. And as the universe expands, distant galaxies moving away from us at great speed. The further the galaxies, the wavelength of the light they emit is stretched (the so-called "red shift"), similar to how the sound of ambulance sirens when it moves away from us.

$ 30 million gap, may not seem like much on the scale of the universe. But it’s like to break the world record for the hundred meter dash. "The champion beats the previous record by just a few hundredths of a second, but they are very important," - said Trent. Receive a daily hot news - download news ticker, be aware of world events.
