GN-z11 is indeed a distant, distant galaxy. According to scientists, it may be the most distant and oldest observed galaxy in the cosmos.
GN-z11 may not have a bright name, but scientists have found that it appears to be the most distant and oldest galaxy ever discovered. Astronomers led by Nobunari Kashikawa, a professor in the Department of Astronomy at the University of Tokyo, are trying to understand how and when it formed.
“According to previous studies, the GN-z11 galaxy appears to be the most distant galaxy detected from us, at 13.4 billion light-years or 134 nonillion kilometers (that’s 134 with 30 zeros). But even just measuring and verifying such a distance is no easy task,” said
To determine how far away GN-z11 is from us, Kashikawa’s team studied redshift – how much light has stretched or shifted toward the red zone of the spectrum. The farther away the space object is from us, the more red its light will be.
The data were obtained using the MOSFIRE instrument at the Keck Observatory in Hawaii.
The study is published in the journal Nature Astronomy.
