 So SkyMapper has been running for a few years now. This project creates a whole digital atlas of the southern sky, including very few but some supermassive black holes. So we were really lucky to discover what now turns out to be the most rapidly growing black hole in the whole universe that we've ever seen. It eats about half a sun of material every single day and it's been doing this for quite a long time. It has already acquired the mass of 20 billion suns. We might think that black holes are supposed to be black, that's their name. And indeed you can't see black holes when they just sit there doing nothing. But in this case, where it's growing as fast as it potentially can, there is so much matter rushing into its throat that it's creating a lot of friction and heat and it's this heat radiation. That is what we see and this is how we discovered it. But if we put this monster into the center of our Milky Way, it would actually shine bright in the sky, many times brighter than the full moon. So this is a monster. Fortunately it's very far away from us, but we're really excited to find objects like this.
