This illustration provided by the European Southern Observatory in February 2024, depicts the record-breaking quasar J059-4351, the bright core of a distant galaxy that is powered by a supermassive black hole. The supermassive black hole, seen here pulling in surrounding matter, has a mass 17 billion times that of the Sun and is growing in mass by the equivalent of another Sun per day, making it the fastest-growing black hole ever known.
