Mysterious threads recorded in the heart of our galaxy: Where do they come from?

No one knows for sure what is hidden in space, and our Milky Way galaxy is full of mysterious magnetic filaments on a new telescopic image made by the South African radio astronomical observatory MeerKAT.

The strands stretch nearly 150 light-years in length and are evenly distributed, and the bizarre structures are several million years old and vary in appearance, writes CNN. Some look like harp strings, waterfalls, and even look like rings around Saturn.

Farhad Youssef-Zadeh, a professor of physics and astronomy at Northwestern University, first discovered the strands 35 years ago via radio waves. He discovered that the filaments were made of electrons from cosmic rays that move their magnetic fields at speeds close to the speed of light. However, the origin of the threads remains a mystery.

Astronomers have now discovered 10 times more strands than the previous discovery, and the research is described in The Astrophysical Journal Letters.

“We have long studied individual strands with myopia,” said Youssef-Zadeh, lead author of the study and a member of the Northwestern Center for Interdisciplinary and Astrophysical Research.

“Now we finally see the big picture – a panoramic view filled with an abundance of threads. Just examining a few threads makes it difficult to draw real conclusions about what they are and where they come from. “This is a turning point in our further understanding of these structures.”

The new, detailed image is actually a mosaic of 20 different observations made over three years, looking at the distant center of the Milky Way, which is 25,000 light-years from Earth.

The amount of radiation varies from other energetic cosmic events, such as supernova remnants, the thread analysis showed. Scientists believe the threads are more likely to be related to past activity caused by a supermassive black hole in the center of the Milky Way, rather than by star explosions. The team also found that magnetic fields are stronger along filaments.

“If, for example, you are from another planet and you meet a very tall person on Earth, you could assume that all people are tall. But if you do statistics on the population of people, you will reach the average height. That is exactly what we are doing. “We can find the strength of magnetic fields, their lengths, their orientation and the spectrum of radiation,” said Youssef-Zadeh.
