Dancing ghosts spotted in deep space
Scientists from the University of Western Sydney and CSIRO and the Australian National Science Agency CSIRO have discovered an unusual phenomenon a billion light-years from Earth. In the pictures, it looked like two “whirling ghosts,” according to Western Sydney University.
The structures revolved around two distant galaxies. The study revealed that they are actually clouds of electrons erupting from two supermassive black holes.
The giant clouds, called PKS 2130-538, were swept by galactic winds. Because of this, the feeling arose that they were moving and “dancing”.
Scientists believe that this discovery will allow them to learn more about the behavior of black holes and the processes taking place in the space between two galaxies.
“However, new discoveries always raise new questions. We still don't know where the wind is blowing from? Why is everything so confusing? And what causes fluxes of radio emission? “, – noted the authors of the scientific work.
The “dancing ghosts” were discovered as part of the Evolutionary Map of the Universe (EMU) project, which is using the new ASKAP telescope to analyze radio sources in space. The telescope is operated by CSIRO and is part of the National Telescope Center of Australia. It uses new technologies to achieve extremely high shooting speeds.
Earlier, with its help, it was possible to find giant rings of radio emission around distant galaxies. They reach about a million light-years across.
“We find surprises in places that we thought we had explored. In the vicinity of the well-known galaxy IC5063, we discovered a giant radio galaxy, one of the largest ever observed, the existence of which no one even suspected, “the scientists noted.
Scientists have previously discovered a “high-speed highway” for galaxies. These are gas filaments tens of millions of light years long.
