Evidence for the first generation of stars to exist in the universe has come to light, thanks to observations made by the James Webb Space Telescope (JWST). The proof is located in one of the most distant galaxies known.
The galaxy, designated GN-z11, was discovered by the Hubble Space Telescope in 2015 and, prior to the launch of the James Webb Space Telescope, it was considered the most faraway galaxy known. With a redshift of 10.6, it makes more sense to talk about how long ago it existed, rather than how far away it is. That's because we see GN-z11 as it was just 430 million years after the Big Bang due to the time it took for its light to travel to our corner of the cosmos. For comparison, the universe today is 13.8 billion years old.
