Quasars are near the extreme high end of this spectrum, but there are other types of AGN that are not quasars. Consider that quasars are so bright because they are almost facing head-on to us.

"The gas in this new type of quasar is moving in two directions: some is moving toward Earth but most of it is moving at high velocities away from us, possibly toward the quasar's black hole ...

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.

By combining data from the Subaru Telescope and James Webb Space Telescope, researchers have discovered distant quasars that are obscured by dust but which may shed light on Little Red Dots.

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...

In April 2023, astronomers announced they had discovered a partnership between two closely bound quasars, representing a merger between galaxies just 3 billion years after the Big Bang. The first ...

Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...

A team of astrophysicists say quasars, some of the most brilliant phenomena in the universe, are likely caused by collisions between galaxies. Quasars are a type of active galactic nuclei; they ...

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. The newly found quasars do ...
