James Webb confirms the discovery of the oldest galaxy - the object appeared 320 million after the Big Bang

The James Webb Space Telescope has helped scientists confirm that JADES-GS-z13-0 is the oldest galaxy ever

This is yet another challenge to modern theories that explainthe evolution of the Universe, individual stars and galaxies.

What is known

In mid-2022, scientists were able to detectfour objects in the early universe. It was one of the first works of the new space observatory. One of the four objects found was the galaxy JADES-GS-z13-0.

After spectral analysis, scientists came toconclusion that JADES-GS-z13-0 is the oldest galaxy ever discovered. It formed 320 million years after the Big Bang. Three other objects were designated JADES-GS-z10-0, JADES-GS-z11-0 and JADES-GS-z12-0. They appeared about 130 Ma after the formation of JADES-GS-z13-0.

All four galaxies were not verymassive. If the Milky Way has a mass of 1.5 trillion solar masses, then each of the four galaxies discovered last year turned out to be only 100 million times more massive than our star. However, three stars are born in them annually.

In conclusion, we add that before the openingJADES-GS-z13-0 GN-z11 was considered the most ancient galaxy. It was discovered by the Hubble Space Telescope about 7 years ago. It appeared 400 million years after the Big Bang.
