“A redshift of one corresponds to a distance of more than 10 billion light-years. JWST’s studies showed that JADES-GS-z14-0 has a redshift of 14.32, the highest ever recorded.”

Wow!

“Usually gases like oxygen show up only after large groups of stars have lived their lives and died in supernova explosions,” Hainline says. “So seeing oxygen in a galaxy this young is like if you are an anthropologist and you find an enormous, ancient city that has evidence of iPhones.”

That just boggles the mind!

Can’t wait to get more data on this wee, spry, bizarre find.

It’s a shame that things like this don’t make national headlines. I sometimes daydream about how cool it would be if we were all collectively interested in these things.

Some theories might allude that such brightness comes from a burgeoning supermassive black hole feasting on gas at the center of JADES-GS-z14-0. But in that case, light is usually concentrated into a much smaller region.

Instead the best explanation Hainline and colleagues have found is that this exceedingly young galaxy has somehow already manufactured about a half billion stars.

. . . How could a galaxy so young have already sparked so many stellar generations? “Usually gases like oxygen show up only after large groups of stars have lived their lives and died in supernova explosions,” Hainline says. “So seeing oxygen in a galaxy this young is like if you are an anthropologist and you find an enormous, ancient city that has evidence of iPhones.”

There was some talk recently that perhaps the universe is as a much as twice as old as we suspected, which could account for (some?) aspects of it we try to explain with dark matter. I wonder if this discovery lends any weight to that?

Wait, if that galaxy didn't form at the exact same point where the big bang happened (we wouldn't see it then), then it is likely older. Or the universe is older.

Does anyone have any good YouTube channels for these type of space discoveries?

But JADES-GS-z14-0 has properties that are vastly different from its slightly ~~older~~ younger counterpart

ftfy... at least, I think that's what they meant.

edit: After discussion, I think I see that I might be a candidate for "people incorrectly correcting others".

That looks like an alien vessel
