Farthest Galaxy Found in Universe


Washington D.C. - Astronomers have established a most distant galaxies and solve the cosmic distance record. It was discovered after researchers using the Hubble Space Telescope to the maximum limits to confirm the existence of galaxies.
The galaxy is 13.4 billion light-years away and into the farthest and oldest objects in the universe. Visible light from that galaxy has started its journey since 400 million years after the Big Bang phenomena occur.
Astronomers measure the distance to the galaxy, named GN-Z11 by splitting light into its component colors. As reported by the Daily Mail on Thursday (03/03/2016), as the universe continues to expand, the object away from the earth extends to the end of the light spectrum of red, a phenomenon known as red shift.
According to scientists, the larger the object is experiencing red shift, the more distant it. Previous astronomers call that EGSY8p7 holds the record red shift at the 8.68 figure, but GN-Z11 defeat with 11.1
A member of the team from Yale University, Dr. Pascal Oesch, said: "We have taken great steps to down time, beyond what we ever expected to use the Hubble Space Telescope."
"We were able to look back to the past to measure the distances of galaxies when the universe was only aged 3 percent today," he added.
GN-Z11 is believed to have a size 25 times smaller than the Milky Way, but growing and 'spawn' new star 20 times faster than our galaxy.
These findings have been published in the Astrophysical Journal and raises many questions. It's the result based on the latest theory, the cosmic evolution of galaxies
even that size can not happen in the past.
Other authors in the journal, Dr. Ivo Labbe, of the University of Leiden Netherlands, said: "The discovery of GN-Z11, shows us that our knowledge of the early universe is still very limited."
"The process of forming GN-Z11 is still a mystery to this day," he added.
A co-authors and a professor of astronomy and astrofikasi at UC Santa Cruz, Garth Illingworth, says his team has used NASA's Hubble Space Telescope to obtain spectroscopic data needed to find a red shift of galaxies. It was used to measure the distance to the earth.
Astronomers think that the Hubble Space Telescope could not find it because they had earlier suspected that only the James Webb Telescope can do.
"It's remarkable that Hubble can do that," says Illingworth.
"This latest discovery shows that the Webb telescope will surely find a lot of young galaxies ..." he added.

Dr. Oesch did not suspect that the Hubbell telescope able to find galaxies that. He said, "We have taken a big step back to the past, more than what we ever expected with Hubble."
Previously, the team had been estimated within GN-Z11 with photometry technique, using a filter to measure the light at different wave with NASA's Hubble Space Telescope and Spitzer.
These findings are interesting preview for the next observation using the James Webb Telescope will be launched into space in 2018.
The findings could also have important consequences for the Wide-Field Infrared Survey Telescope (WFRIRST) NASA, which will have the ability to find other galaxies that have a long distance.
