"Webb" considered the most distant galaxy in the universe. She has an abnormal mass

An international team of astronomers used the James Webb Space Telescope to

images of the galaxy GN-z11 in the nearinfrared range. It is one of the most distant objects known to date. The results of the observations provided scientists with important information about the morphology and environment of GN-z11.

The redshift of an object is approximately10.6, size - about 4,000 ± 2,000 light years, and a stellar mass - 1.3 billion Suns. Now scientists are observing the galaxy as it existed 13.4 billion years ago, just 430 million years after the Big Bang.

GN-z11 is a particularly bright galaxy in whichinhabited by young stars about 90 million years old (for comparison, the age of the Sun is 4.6 billion years). It is noteworthy that the galaxy has an anomalously large stellar mass for such a young age, which suggests its rapid growth.

Also, the brightness of the GN-z11 allows you to observe it evenusing ground-based observatories. However, a team of astronomers led by Sandro Taccella of the University of Cambridge, UK, studied the galaxy using the James Webb Near Infrared Camera (NIRCam). The observational campaign was carried out as part of the Advanced Deep Extragalactic Survey (JADES) program.

Studying the properties of the most distant galaxies hascrucial to expanding scientists' knowledge of the early stages of formation and evolution, including the formation of the first stars and black holes. Astronomers perceive such galaxies as probes for a number of baryon processes, structure formation and the nature of dark matter.
