Webb telescope may have already found most distant known galaxy – GLASS-z13

Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday.

Known as GLASS-z13, the galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told AFP.

Well shit.

I’m probably way out of touch on this but I thought the orthodoxy was that galaxies didn’t form until nearly a billion years after the bb.

Yes, it may have.

That’s a good point. I’ll look it up.

I can’t imagine how a galaxy would be visible from before the start of the era of re-ionisation.

That’s too big as well. The first galaxies were supposed to be small, about … 10 billion times greater than our sun. Oops. I stand corrected.
