South African Radio Telescope Reveals Intergalactic Cosmic Trails
The MeerKAT radio telescope, located in the province of the Northern Cape, has produced a remarkable image showing a combination of cosmic features never before seen, revealing unexpected details of the inner workings of enormous radio galaxies, writes Elsabé Brits for Daily Maverick.
These striking features - cosmic "threads, ribbons and rings" - are much larger than our own Milky Way. At the centre of the giant elliptical galaxy called IC 4296 is a rotating black hole with a mass of a billion suns. Energy released by matter falling onto the black hole generates two opposing radio jets containing magnetic fields and relativistic electrons.
After travelling through intergalactic space at the speed of light for 160 million years, these radio waves were detected by the South African Radio Astronomy Observatory's (Sarao's) MeerKAT telescope, which is in the Karoo region of Northern Cape.
