00:00The James Webb Space Telescope has given us some absolutely jaw-dropping images of deep space so far.
00:10From eerie spiral galaxies to the furthest looks back in time to when the universe was still in its infancy.
00:15Now NASA's newest space telescope is making discoveries, and it has just identified the four furthest galaxies ever observed.
00:22They don't look like much, just little specks in a sea of black, and, well, other little specks.
00:27But the oldest of 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.
00:36That period of time is called the epoch of reionization, an excitatory time in the universe's history when the first stars were emerging into being.
00:43And 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, for reference, the Milky Way weighs 1.5 trillion solar masses.
00:55And they likely have very low metal content as well.
00:58That's because the closer in time a galaxy is to having been formed after the Big Bang, the lower its metal composition tends to be.
01:04As metal forms in stars, and there were simply fewer of them.
01:07And there was a series of series of images to play in time, and it was such a real complex kind that were perceived, at least one of the cautionaries, within the
01:20grass table in another line.
01:23That was so hard and neat.
01:24And it was then the greatest way that needed to slow down.
01:26And now, at least the point in time of the ocean fĆ­sica is the answer in time ofŲ§Ų² lorsqu terrorism.
