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

New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive supermassive black hole binary paintings than other galaxies.

The quasars are powered by black holes that are up to ten billion times the mass of the Sun. The black hole's gravity pulls in matter which forms a rotating disk around the black hole called an ...

Seeing red To better understand the exact role quasars played during the Epoch of Reionization, astronomers are searching for quasars in this early and distant era of the universe.

Blazar FAQs What is the difference between quasars and blazars? Quasars and blazars are the same objects — galaxies harboring supermassive black holes with jets pointing in opposite directions.

The Gemini North telescope and Subaru Telescope have been used to discover most distant merging quasars yet, "seen over 900 ...

Quasars – the brightest and most powerful objects in the Universe – are ignited when galaxies collide, astronomers have said. These celestial objects can be a trillion times brighter than the ...

The two active supermassive black holes are the most distant pair of quasars ever seen and shed more light on how the universe transformed into what it is today.

Astronomers just solved a 60-year mystery regarding the brightest objects in the universe Until now, no one knew for sure what quasars — among the most massive explosions in the universe ...

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 ...

A new study reveals that supermassive black holes at the centers of galaxies, known as quasars, can sometimes be obscured by dense clouds of gas and dust in their host galaxies.
