A tightly packed galaxy 25 million light-years distant was discovered by NASA’s James Webb Space Telescope (JWST).
For the first time, scientists headed by University of Edinburgh specialists utilized the world’s most costly telescope to unveil GS-9209’s features.
Dr. Adam Carnall of the University of Edinburgh’s School of Physics and Astronomy remarked, “The James Webb Space Telescope has already demonstrated that galaxies were growing larger and earlier than we ever suspected during the first billion years of cosmic history.”
GS-9209, the first known galaxy, developed 600 to 800 million years after the Big Bang.
This investigation provides us our first thorough look at the features of these early galaxies, documenting the evolution of GS-9209, which formed as many stars as our Milky Way just 800 million years after the Big Bang.
‘The fact that we also detect a very enormous black hole in this galaxy was a great surprise, and gives a lot of weight to the concept that these black holes are what shut down star formation in early galaxies.’
Despite being 10 times smaller than the Milky Way, GS-9209 has a similar amount of stars.
Their aggregate mass is 40 billion times that of our sun, and they were produced swiftly before star production in GS-9209 ceased, according to the Nature research.
Quiescent galaxies like GS-9209 are the oldest known.
