The most luminous objects in the universe keep getting more mysterious.
Astronomers have discovered a new type of quasar — an incredibly bright galactic core powered by a supermassive black hole — that current theory fails to predict.
Models predict that a quasar's light and heat should push nearby gas out from the center and toward the fringes of the host galaxy.
