The James Webb Space Telescope was built primarily to transform our understanding of the early universe.
Not only did it live up to the expectations, it also surpassed the hype surrounding it by finding galaxies earlier in the universe than any seen before.
But the telescope has another less talked about goal, and that is probing those earliest moments after the big bang 13.8 billion years ago.
It has begun hunting for signs of the first stars to switch on in the universe, the so-called Population 3 stars, gigantic balls of fire purely made of hydrogen and helium that shined brilliant and brightly to bring the first light to the universe.
So far, we haven’t had any possible detection of such stars, but they must exist as per our models. But now, using the JWST, two teams of astronomers have reported promising signs of Population 3 stars.
