Summ:

  • The James Webb Space Telescope (JWST) has discovered the most distant galaxy ever confirmed, named JADES-GS-z14-0, which appears as it existed just 290 million years after the Big Bang.

  • The discovery of this surprisingly luminous and massive early galaxy challenges theories about how galaxies formed in the cosmic dawn

  • JWST has been repeatedly breaking its own records for the most distant galaxies since beginning operations in 2022

    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.”

    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”.

    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.

    “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.

        Ha ha ha!

        Well…

        We both saw the photo in the article. It’s a big photo, and they had to enlarge the teeny tiny spot this galaxy was in, then blow it up and actually add an arrow to point it out.

        Seems pretty wee to me!
