As long as 16,000 light years, the large -scale structure is measured by China Eye, or a new rotary arm of the galaxy

The mysterious celestial bodies in space may be the new arms of the galaxy

Scientists discover giant structures at the outer edge of the galaxy.

The impression of the galaxy in the eyes of the artist. Our galaxy is composed of huge rotary arms.

Astronomers discovered a new fiber structure composed of gas and dust from the periphery of the galaxy. The characteristics of the new structure of this nickname "Cattail" have not been fully drawn, but found that its team believes that it may be an unknown arms in our galaxy.

The Galaxy is a huge rotal galaxy. It has a central raised and surrounded by a vortex arm composed of stars, gases and dust. According to NASA, our galaxy has been proven four rotary arms-two of them are called Shield-Half-Half-Heman Arms and British Ferry Berset, and the other two small rotary arms are squeezed between them, They are torque arms and horses. The earth is on the branches of human arms.

Professor Qiu Keping, a astronomer of Nanjing University, revealed to the "Live Science" that in the past few years, the world's largest radio telescope, the 500 -meter -caliber spherical telescope (FAST) in Guizhou Province, China, has been Systematic research on the sky area of ​​Swanz X.

Professor Qiu also mentioned that Fast observes the universe through the radio part of the electromagnetic spectrum, so it is particularly effective for observing the air -conditioned clouds containing hydrogen. When observing the Swan seat X, Professor Qiu and his colleagues noticed that there seemed to be far away behind it. Swan seat X is a huge star formed, about 4,500 light years from Earth.

By combining FAST observation results with Germany and another long -term telescope in Australia, researchers can draw their characteristics. This is about 68,000 light years from the earth and extending nearly 3,600 light years. The farthest giant gas fiber structure.

The team predicts that the quality of "Mugu" is equivalent to 65,000 sun, and its actual range may be larger, and it may even be up to 16,000 light years. The discovery was described in an article published in the ARXIV pre -print database on August 4, 2021, which has been approved in the "Celestial Physics Magazine Newsletter".

"Tugu" is located in the outer edge of the galaxy, and is about three times the distance from the center of the galaxy. Most of our celestial bodies in our galaxy are close to the center, so this huge structure is a bit puzzling.

Professor Qiu said: "We don't know how such a giant fibrous gas structure is formed in such an extreme position."

At present, he and his colleagues cannot determine whether "Tugu" is an independent gas fiber structure or wrapped in the main body of the galaxy and connects somewhere. It may be an unknown rotary arms, or it may be a branch of a one of the four main rotary arm. Professor Qiu said.

There are still many questions about this structure. Our edge of our galaxy is considered distorted, but "Tugu" does not seem to follow the same distortion mode. Professor Qiu pointed out that he and his team planned to further observe this structure with FAST in order to have a good understanding of it.

"He reminded me that there are still many things we don't know about the galaxy." Felix J. Rockman, a astronomer on the Green Bank Observatory of West Virginia, did not participate in the work, but he told "Science Scene" "Every time we seem to see more far, but there will always be more information waiting for us to discover."

He also mentioned that because Fast provides a better resolution than previous radio telescopes, "Mugu" is likely to be part of the previously not noticed in the Milky Way. The characteristics of this structure do not follow this area's galaxy distortion. It is strange that there is still controversy despite the exact details of the twisted.
