Dark Heart of the Nearest Radio Galaxy

Distance scales uncovered in the Centaurus A jet. The top left image shows how the jet disperses into gas clouds that emit radio waves. The top right panel displays a color composite image, with a 40⨉ zoom compared to the first panel to match the size of the galaxy itself. The next panel below shows a 165 000⨉ zoom image of the inner radio jet.The bottom panel depicts the new highest resolution image of the jet launching region obtained with the EHT at millimeter wavelengths with a 60 000 000⨉ zoom in telescope resolution. One light year is equal to the distance that light travels within one year: about nine trillion kilometers.
