Astronomers spot unusual structures in deep space

An international team of astronomers has recorded unusual “ghostly” structures that surround distant galaxies. An article about the study was published on the official website of the University of Western Sydney.

Scientists discovered unusual space structures during the first deep survey of the sky using the ASKAP CSIRO radio telescope (Australian SKA Pathfinder Telescope). The authors of the study found that the clouds are composed of electrons. These giant structures surround galaxies a billion light-years away.

Visually, these giant clouds of electrons resemble two ghosts, which seem to be in a dance. Accordingly, the structures are called so – dancing ghosts.

As noted by Professor Ray Norris, at first, scientists did not understand where huge electron clouds appeared in space. However, they later discovered their parent galaxies. As the authors of the study note, supermassive black holes in the centers of galaxies eject jets of electrons into space, which take different forms under the influence of the intergalactic wind.

In the vicinity of the well-studied galaxy IC5063, scientists also discovered a giant radio galaxy, one of the largest known, the existence of which astronomers previously did not suspect. Its supermassive black hole spawns jets of electrons nearly 5 million light years long. ASKAP is the only telescope in the world that can record such a phenomenon, scientists conclude.
