Vikas Chander, taken from El Sauce Observatory in the Hurtado River Valley, Chile

At just 12 million light-years away, Centaurus A (NGC 5128) is the closest active galaxy to us, with a supermassive black hole at its core ejecting material into the intergalactic medium. It is well known that these jets of material can be seen in radio emission as huge lobes on either side of the galaxy. However, this Hα/OIII/LRGB image taken from the Atacama Desert in Chile with a 24-inch robotic telescope (and nearly 24 hours of exposure) offers a detailed view of the ejections in visible light at the lower right.
