What is this mysterious fiber structure found on the edge of the Milky Way?

Is the Milky Way different from the representations we know? A team of researchers from Nanjing University in China discovered the powerful thanks Radiation telescope Spherical (fast) with an opening of 500 m Five hundred meter hole sphere Radio Telescope), A fiber structure extending to an area far from the center Galaxy, At 71.754 Light years. A study, Posted in Front axle August 5This discovery led to two hypotheses that could explain the existence of this mystery Cloud : A great thread Gas To date no galaxy has been found in or near the Milky Way.

A great puzzle

The origin of this thread, named கட்டைல் (Or “guenuil” in French), so to be determined. But the Astronomers Scientists have developed two hypotheses that could explain the existence of this gas cloud, which was accidentally revealed during observation. Cygnus X radio source, In Constellation அன்னத்தின். First, the kettle may be a large molecular fiber made up of gases such as hydrogen, about 5 kilobarsecs in length. It forms one of the most important molecular clouds to be found nearby Milky Way. By comparison, 5 kpc equals 16,307.8 light-years. One light year equals 9.460 billion kilometers, ours The Solar System Covering only 20 billion kilometers.

Chinese astronomers looked at the speed of the thread, and their study illustrates how fast it moves. Speed Oscillates at 160 to 140 kilometers per second. This structure is located long enough behind one arm The center of the Milky Way, Called cu-Croix. Its proximity and its speed made researchers hesitate for a long time: is a dwarf galaxy invisible? By making additional observations, the second possible theory is a new theory of our galaxy that radio telescopes and other instruments could not detect due to lack of power. If this hypothesis is confirmed, it means that this new “branch” of the Milky Way will be located outside the galaxy named in English. Intense outer galaxy. This possibility will be interesting to scientists, as fields far from galaxies are real nurseries for young people. Stars.

Fast in support

This invention necessitated the use of a high-speed radio telescope. The device, installed in China’s Guizhou province, went into operation in 2020, bypassing initial monitoring Prior to 2016. Creates a dome with a diameter of 500 meters Of Fu Arecibo, Made up of 4,500 metal panels that pick up fast different signals Wavelengths, Varying from 70 MHz to 3 GHz. Thanks to its accuracy, the radio telescope in particular has become a staple in hunting pulsars: in May 2021, it invented the 201.

Faust’s accuracy can explain the late detection of a hand in the Milky Way, where other older radio telescopes could not detect an element Localization Or hidden by someone else. However, there is no doubt about it Astronomical physicists To unravel the mystery of this strange gas structure they have to turn their eyes from the University of Nanjing and the parable of the fast to the jungle.
