Researchers measure and confirm the distance to oldest, farthest galaxy GN-z11 in the universe The team of researchers measured the redshift of GN-z11, which is the light stretches out, becomes redder, the farther it travels. Dec 18, 2020 10:14:31 IST Researchers from the University of Tokyo have now accurately measured the distance to the oldest and furthermost galaxy that has ever been detected. As per a statement released by the university, a team of astronomers used the Keck I telescope to measure the distance to the ancient GN-z11 galaxy. The galaxy is distant it defines the actual boundary of the universe that we have been able to observe. According to the authors, the study could shed light on a period in the history of the universe when it was relatively young -- being only a few hundred million years old.
