(CNNEspañol) – Taking the Hubble telescope to its limits, an international team of astronomers broke the record cosmic distance, reaching to observe the most distant in the universe galaxy, of which are known so far, NASA reported.
This galaxy, called GN-z11, has existed for 400 million years after the Big Bang and is 13,400 million light years from Earth.
Although dimly perceived, it is an unusually bright galaxy, given its distance from Earth.
“We have taken a giant step back in time, far beyond what we thought was possible with the Hubble. We were able to look to the past to observe a galaxy that existed when the universe was just a 3% of its current age, “said researcher Pascal Oesch, University of Yale.
Astronomers are now closer to the first galaxies that formed in the universe, according to NASA.
The new Hubble observations leads astronomers to land that was thought could only be achieved by the future James Webb Telescope.
This measurement provides strong evidence that other bright galaxies previously detected by Hubble eel are extraordinary distances.
Previously, astronomers had calculated the distance GN-z11 analyzing its color, captured in images taken by the Hubble and the Spitzer telescope NASA. Now, for the first time for such a remote galaxy, astronomers used Hubble camera to accurately measure the distance to the galaxy is spectroscopically, fractionating the light to decompose all its component colors.
“It is surprising that such a massive galaxy was only 200 to 300 million years after the first stars began to form. A very rapid growth is needed, producing stars at a tremendous speed, so that a galaxy of 1,000 million solar masses as soon forme “explained researcher Garth Illingworth of the University of California, Santa Cruz.
