00:00The James Webb Space Telescope has given us some absolutely jaw-dropping images of deep
00:08space so far. From eerie spiral galaxies to the furthest looks back in time to when the
00:13universe was still in its infancy. Now NASA's newest space telescope is making discoveries,
00:18and it has just identified the four furthest galaxies ever observed. They don't look like
00:23much, just little specks in a sea of black, and well, other little specks. But the oldest
00:27of these galaxies is believed to have formed just 320 million years after the Big Bang.
00:33That means they were formed around 13 billion years ago. That period of time is called the
00:37epoch of reionization, an excitatory time in the universe's history when the first stars
00:42were emerging into being. And that might be why all four of them are rather small galaxies.
00:46None of the galaxies weighs more than 100 million solar masses, which one of the researchers says
00:51for reference, the Milky Way weighs 1.5 trillion solar masses. And they likely have very low
00:56metal content as well. That's because the closer in time a galaxy is to having been formed after
01:01the Big Bang, the lower its metal composition tends to be, as metal forms in stars. And there
01:05were simply fewer of them.
01:07Yes, increased inflation currents.
01:12Anyway.
01:13Thank you very much.
01:16Yup.
