An unusual sight around a black hole. Objects 16 times the size of the moon

Centarus A is an active galaxy 12 million light-years away from the Milky Way. In its center is a huge black hole, the mass of which is estimated at 55 million times the mass of the Sun. So it is strong and “spits” plasma jetsAstronomers were able to take very detailed pictures.

Radio wave jets from the black hole galaxy Centaurus A.

The human eye is not able to see this black hole, but thanks to specialized tools, it was possible to capture it through radio waves. In this way, images were obtained showing plasma jets extending up to 8 degrees from the sky. this is 16 times more than a full moon.

The captured images show jets over a million light-years long. The bright spots in the background are not stars, but other galaxies located farther away than the Milky Way. This effect was achieved thanks to the Murchison Widefield Array (MWA) radio telescope in the western part of Australia. It consists of 4,096 antennas.

At the same time, we invite you to listen to the latest episode of the podcast from a technical point of view. This time we spoke with the creator of Jetson ONE – a passenger drone that has a chance to revolutionize the concept of personal transportation. How does an air craft work, how much does it cost and can the average Kowalski fly in it?
