When astronomers first turned on the James Webb Space Telescope and pointed it out into the black of space, it revealed galaxies that are billions of years old, those that were more or less formed at the dawn of the universe itself. Now experts say that one of them, which they estimate is around 13 billion-years-old, is a bit of an enigma as it shouldn’t exist at all.

00:00When astronomers first turned on the James Webb Space Telescope and pointed it out into the block
00:08of space, one of the first images they got was this one. It shows galaxies that are billions
00:13of years old, those that were more or less formed at the dawn of the universe itself.
00:18Now experts say this one, which they estimate is around 13 billion years old, is a bit of an
00:24enigma, as it shouldn't exist at all. It's called ZF-UDS-7329, and astronomers say the galaxy
00:32is too complex to have been created in the early days after the Big Bang. The issue is
00:36it's around the size of the Milky Way, but it also has around four times the number of
00:40stars by mass. The issue arises because our current dark matter model suggests that it
00:45was not in a state to support galaxies of this size at that time, as it was too smooth.
00:49Those same models outlined that as time went on, dark matter ripples grew because of gravity.
00:53collecting in larger clusters and dragging other elements, namely hydrogen, together
00:58with it, thus allowing it to create larger, more complex galaxies.
01:02Another peculiarity about the galaxy is that it doesn't seem to have changed much after
01:06its creation. The study's authors say this challenges the standard model of cosmology,
01:11adding quote, the key question now is how they form so fast very early in the universe, and
01:15what mysterious mechanisms lead to stopping them from forming stars abruptly, when the rest
01:20of the universe is doing so.
01:23Do not accept it as to chop the elegance of the galaxy's.
01:26Do not accept it as a temperate as a white-catch.
01:28There are a few things that can't make it better than that.
01:29And that is the fact that you can create and you can imagine a mixture of the sea.
01:30There are very many things that can become a legend of astrology.
01:30There are some things that can happen.
01:32There are many points that could be used to be used by the dark, but there are some things that
01:35have to be used in the dark as well.
01:36There are many points that can be used to be used in it to form a connection to the
01:44surface of the galaxy.
