Black holes formed quasars less than a billion years after Big Bang
A surprisingly normal looking quasar when the Universe was 750 million years old.
In the latest example, researchers have used the Webb to characterize a quasar powered by a supermassive black hole as it existed approximately 750 million years after the Big Bang. Due to that distance, features are hard to resolve, and the redshift caused by the Universe's expansion takes the intense UV radiation from many elements and stretches them deep into the infrared. Despite the oddities, this object looks a lot like quasars in more recent times: "Our observations demonstrate that the complex structures of the dusty torus and the [accretion disk] can establish themselves around a [supermassive black hole] less than 760 Myr after the Big Bang."
