Four Galaxies Observed in the Early Universe

In the short time since the summer of 2022, countless discoveries have been made possible. James Webb Space Telescopehosted another one of these today. The team, which includes scientists from many nationalities, discovered four of the galaxies closest to the Big Bang.

It was shared that the discovered galaxies are 300 to 500 million years away from the Big Bang. So these galaxies, our universe, which is about 13.8 billion years old, is yet to come. when you’re in 2% of your life had occurred.

The closest galaxy to the Big Bang is 320 million years away:

Of the four galaxies, the one closest to the Big Bang is named JADES-GS-z13-0. Galaxy from the beginning of the universe occurred 320 million years later. is estimated. Another galaxy, JADES-GS-z10-0, is said to have formed 450 million years later. This galaxy was previously observed by the Hubble Space Telescope.

The four galaxies have something in common and surprising:

It was announced that the mass of all four galaxies is almost equal to the mass of 100 million Suns. This value represents galaxies “very low mass” category. For comparison, our Milky Way Galaxy has the mass of 1.5 trillion Suns.

Galaxies, on the other hand, have a high rate of star formation despite being in the early universe. Even the stars are with the stars in the Milky Way Galaxy. almost the same speed is occurring. This is considered quite surprising for conditions in the early universe.

Galaxies also support a theory about the universe. The accepted standard model theory of the universe, the closer to the Big Bang. that there is so little metal suggests. Supporting the theory, all four newly observed galaxies are extremely poor in metal density.

None of the discovered galaxies is the closest galaxy to the Big Bang. The James Webb Space Telescope has also enabled us to explore a galaxy just 230 million years away in recent months.
