The collection of stars known as GLASS-z13, dates back to 300 million years after the Big Bang.
This beats the previous oldest galaxy, spotted by the Hubble Space Telescope, by about 100 million years.
The universe formed 13.8 billion years ago but was initially dark, taking a while for matter to clump together in such dense formations that stars eventually burst into life. It was spotted in the early telescope data released last week from NASA’s James Webb observatory which is scanning the universe from about 1.6 million kilometres from Earth.
“So we don’t know exactly when that happened, the models show somewhere between 150 million and 300 million years after the Big Bang.“So we think that looking about 300 million years after the origin of the universe, what we will be seeing is the first stars and the first galaxies forming.”The new images are possible because the James Webb telescope contains instruments that can capture light in the infra-red spectrum.
