In the center of the milky Way discovered giant bubbles

In the vastness of the milky Way galaxy hides many mysteries.
Scientists found in the center of the milky Way galaxy population with cosmic structures private radio emission. in its form resembles a giant hourglass or bubbles which emit radiation and which, according to the researchers, should not be there. These mysterious structures are located above and below the Central region of our galaxy. On opening an international group of scientists, and the study published .
What is in the center of the milky Way galaxy?
In the early 1980-ies, the astronomer Farhad Yusef-Zadeh, Professor of physics and astronomy at northwestern University, observed the center of the milky way when I found a strange thin structure, which emits its own radiation. He suggested that the reason for problems in the telescope, which has clouded the field of view, and that no oddities in the center of the milky Way. Then struck observations about the structures of their data. However, upon further observation, this strangeness has not disappeared anywhere, but it soon became clear that what the astronomer was mistaken for a fault in the telescope, was the whole population of cosmic structures in the heart of the galaxy.
Since it was discovered more than a hundred of fine structures in the center of the milky Way. Astronomers cannot fully explain what they are, but still give the structures of familiar, earthly names: Pelican, mouse, snake. The menagerie was set around a supermassive black hole in .
look like space bubbles
Recently we wrote about the fact that the supermassive black hole at the center of the milky Way behaves quite strange. Experts note that despite the recently recorded change the brightness of the event horizon of a black hole like objects in other galaxies behave much more active. Discovered structure, we will call them simply the bubbles extend in different directions from the black hole at 1400 light years. Outwardly the bubbles resemble two halves of an hourglass, the center of which is a black hole.
Where did the giant bubbles in the center of the galaxy
Observations obtained with the telescope of the South African MeerKAT radio astronomy Observatory (SARAO). With the help of this tool, in the study, astronomers have pieced together a picture of the center . After opening the bubbles, the researchers were looking for a special type of radiation, generated in the turbulent regions of space — it is a region in which electrons move at a speed close to the speed of light and interact with powerful magnetic fields. It creates radio waves that is able to illuminate the space structure in the vicinity. Scientists were able to capture this radiation.

By Examining bubbles that resemble a work of cosmic art experts came to the conclusion that they are the result of a cataclysm that occurred millions of years ago for a very short period of time. Thus, one possible explanation for the appearance of giant bubbles could be , which made the environment a huge amount of energy. It is also possible that the reason was the outbreak of a black hole. The fact that sometimes black holes consume nearby star the material too quickly and they have to get rid of it.
Despite the fact that the behavior of the black hole at the center of the milky Way cannot be called active, astronomers do not exclude that the active phase in the past. Regardless of the real reasons the event was so powerful that surge of energy, which, in the words of the researchers, literally broke through the interstellar medium. An ancient explosion blew the bubbles and as they expand, excited electrons which interact with magnetic fields produce radio waves that are found by scientists.
What other bubbles are there in space?
It May come as a surprise, but the heart of our galaxy is home to other bubbles. Bubbles , named in honor of the great scientist of the 20th century, extend about 25 thousand light-years above and below the galactic center. Astronomers discovered them almost ten years ago with the help of a space telescope designed to detect gamma rays. Their nature, experts are trying to understand today.
A Team of scientists who worked on the study, do not exclude, that in space there can be a lot more bubbles. This means that puzzles in the shape of a Pelican or an hourglass in the vastness of the observable Universe a lot more. As soon as our telescopes collect data, a picture of outer space around us is becoming more clear.
