With the help of the Chinese spherical radio telescope with a FAST aperture of five hundred meters, a huge structure of atomic gas in the universe was discovered.
As reported by Ukrinform, this was reported by Xinhua.
The discovery was made when scientists pointed the world’s largest radio telescope, FAST, at Stefan Quintet, a group of five galaxies, four of which form a compact galaxy cluster.
It is noted that the linear scale of the discovered structure of atomic hydrogen gas reaches about two million light-years or 0.6 megaparsecs, making it the largest structure of its kind discovered in the universe.
According to astronomers, this structure probably arose as a result of tidal interactions during the early stages of the Stefan Quintet’s formation.
The results provided new insights into understanding the evolution of galaxies and their gasses in space. However, it is still unclear why atomic gas with such a low density is not destroyed by ultraviolet radiation in the cosmic background.
NASA’s James Webb Space Telescope recently captured an image from Stefan Quintet that shows in detail how interacting galaxies trigger star formation within each other.
As reported by Ukrinform, the James Webb space telescope took a detailed photograph of the Pillars of Creation in the Eagle Nebula.
