NGC 1566 is a spiral galaxy located about 40 million light years away towards the constellation Doradus, the Dolphinfish. It lacks a barred central region, but still not entirely unbarred, classifying it as an intermediate spiral. The galaxy is also the brightest and most dominant in the Doradus group of galaxies, and the second brightest Seyfert galaxy known.
Seyfert galaxies have extremely bright nuclei, thought to be caused by housing a supermassive black hole. These structures, millions of times more massive than our Sun, emit strong bursts of radiation that light up the core. This image by Spitzer shows the galaxy in infrared light, with blue marking older stars and red indicating active star formation.
