Farthest Galaxy in the Universe spotted? Scientists claims so!! Know the truth here!
New Delhi, 26/12: Scientists claim that they have discovered what they think is the farthest and oldest galaxy ever observed.
The alleged galaxy is named Galaxy GN-z11, and it appears to be the most distant and oldest galaxy ever spotted. Astronomers led by Nobunari Kashikawa, a professor in the department of astronomy at the University of Tokyo, embarked on a mission to find the universe’s most distant observable galaxy.
“From previous studies, the galaxy GN-z11 seems to be the farthest detectable galaxy from us, at 13.4 billion light-years, or 134 nonillion kilometers (that’s 134 followed by 30 zeros),” Kashikawa said in a statement. “But measuring and verifying such a distance is not an easy task.
To determine Galaxy GN-z11’s distance from Earth Nobunari Kashikawa’s team studied the galaxy’s redshift — how much its light has stretched out, or shifted toward the red end of the spectrum. In general, the farther away a cosmic object is from us on Earth, the more redshifted its light will be. Additionally, the team looked at GN-z11’s emission lines — observable, chemical signatures in the light coming from cosmic objects.
