This is one of my favourite galaxy targets - NGC1365 - a barred spiral galaxy about 74 million light years away in the southern sky constellation of Fornax. At the centre of this galaxy is a supermassive black hole at a whopping 2 million solar masses (or approx 670,000,000,000x the mass of the Earth), which also rotates at close to the speed of light (!!) Mind boggling really.
