CEERS2-588 is a dwarf spheroidal galaxy, only 3,000 light-years across, about 100 times smaller than our Milky Way. Despite its small size, CEERS2-588 hosts a supermassive black hole with a mass 50 million times that of our Sun. The ratio of the black hole mass to the galaxy mass in CEERS2-588 is the highest ever observed.
