Discovered the most distant galaxy in the universe – Diario Digital Juárez

Washington Astronomers announced the discovery of the most distant galaxy, a real factory of stars when the universe was just 400 million years.

Through the use of a different technique which had aroused some skepticism, a team of astronomers shed light on a period in the evolution of the universe that was supposed impossible to observe with current technology.

they used the Hubble Space telescope and found a signal wavelength of an extremely bright galaxy 13 billion 400 million light years, according to a study published yesterday by Astrophysical Journal.

with that signal light, astronomers could semiborrosa produce a photograph of this galaxy. It seems dark and amorphous, but actually emits a bright blue light, but the light has traveled so long through such a distance that has changed towards the end of the solar spectrum to dark red. The galaxy is an incubator of stars ten times more active than our Milky Way, said Gabriel Brammer, study co-author and astronomer at the Scientific Institute of Space Telescope.

“It creates stars frantically” he said.

If we could take us back in time to approach the new galaxy (named GN-z11), we would see “young blue stars and really bright,” and around us “objects very chaotic appearance” that are forming galaxies, he said co-author Garth Illingworth of the University of California, Santa Cruz.

astronomers measure the distance of objects by calculating the rate of change of light from blue to red of the electromagnetic spectrum, astronomers call redshift or “redshift”.

the new discovery surpasses all efforts of competing groups of astronomers who sought a “redshift” of 9, said study lead author, Pascal Oesch, Yale.

A competitor astronomer Richard Ellis, at the European Southern Observatory, who held the previous record, expressed skepticism.
