Scientists use the "China Sky Eye" Fast to discover a huge atomic gas structure with a scale of about 2 million light years, which is 20 times larger than the Milky Way.This is the largest atomic gas structure detected in the universe so far.

According to Xinhua News Agency, the study was completed by the international team led by Xu Cong, a researcher at the National Observatory of the Chinese Academy of Sciences. The relevant results were published online on October 19th.

"This discovery thanks to the unprecedented extremely dark celestial detection ability brought by the" China Sky Eye '"super high sensitivity." Xu Cong said that "Chinese Eye" can detect extremely thinness away from the center of the galaxy center.The dull radiation emitted by the scattered atomic gas opened a brand new window for studying the origin of the celestial body in the universe.

According to reports, the origin of all celestial bodies in the universe is inseparable from atomic gas. For example, the main evolution process of the galaxy is the process of constantly absorbing atomic gas from the space space and then transforming it into a star.Observing the gas in the universe is a very important research topic in the field of celestial physics.

"Stephen's Five Age" has been the most watched galaxy group in the field of astronomy since its discovery in 1877.This latest discovery shows that there is a large -scale low -density atomic gas structure at the peripheral space away from the center of the galaxy group.The formation of these gas structures is likely to be related to the early formation of the "Stephen Five Staries". The historical history of galaxy interaction has been about 1 billion years.

"This discovery has challenged the evolution of the research galaxy and its gas in the universe, because it is difficult to explain why existing theories are difficult to explain why these thin atomic gases have not been by the universeThe ultraviolet background radiation is off in the space. "Xu Cong said that the observation results also foreshadowed that there may be more such large -scale low -density atomic gas structures in the universe.
