The giant elliptical galaxy NGC 5128 is the radio source known as Centaurus A. Vast radio-emitting lobes (shown as orange in this optical/radio composite) extend nearly a million light-years from the galaxy. Credit: Capella Observatory
A new image taken by an array of radio telescopes is the best resolution view ever of particle jets erupting from a supermassive black hole in a nearby galaxy. An international team of astronomers targeted Centaurus A (Cen A), and the image shows a region less than 4.2 light-years across — less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the most detailed image yet of black hole jets.
