James Webb Space Telescope identifies galaxy GS-9209 — 25 billion light years away
Astronomers have used the most powerful telescope ever built to identify a massive, densely packed galaxy 25 billion light years away.
Known as GS-9209, the galaxy formed about 600 million to 800 million years after the Big Bang, and is the earliest of its kind found to date, researchers say.
The scientists, led by University of Edinburgh experts, used the James Webb Space Telescope (JWST) to reveal the properties of GS-9209 for the first time.
Dr Adam Carnall, of the University of Edinburgh’s School of Physics and Astronomy, the lead researcher, said: “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.
“This work gives us our first
