An IRAS 13224-3809 is a supermassive black hole that is located in the center of a galaxy. A black hole is an object in space that is so dense and has so much gravity that nothing can escape from it, not even light! Imagine it like a big vacuum cleaner that sucks in everything around it. This black hole is supermassive because it is really big and has a lot of mass - like a giant elephant compared to a tiny mouse. Scientists study these black holes to learn more about how the universe works and to understand more about what happens to matter and energy when it gets too close to a black hole.
