You might have heard of Quasars or have a vague idea of what they are, but the incredible reality of these monsters from long ...

The difference between blazars and quasars comes down to the viewing angle. For blazars, we are looking down the length of the jet, whereas for quasars, the jet is pointed at a different angle.

Plenty of groups have been theorizing about primordial black holes (PBHs) recently. That is in part because of their ...

Quasars are among the most powerful and mysterious objects in the universe,bright, energetic beacons powered by supermassive black holes. Recently, astronomers discovered the largest and most ...

Quasars, the brightest objects in the cosmos, could act as cosmic signposts, directing astronomers to elusive pairs of supermassive black holes. New research suggests that quasars — the luminous ...

This illustration depicts two quasars in the process of merging. Using both the Gemini North telescope, one half of the International Gemini Observatory, which is supported in part by the US ...

The newly discovered double quasar, J121503.42–014858.7 and J121503.55–014859.3 — referred to as C1 and C2 by their discoverers — was spotted using the Subaru Telescope on Hawaii's Mauna ...

"Quasars are one of the most extreme phenomena in the Universe, and what we see is likely to represent the future of our own Milky Way galaxy when it collides with the Andromeda galaxy in about ...

Although quasars turn off, transitioning into mere galaxies, the process should take 10,000 years or more. This quasar appeared to have shut down in less than 10 years — a cosmic eyeblink.

The quasars could also have passed behind something that's blocking their signals -- but, as with everything about this case, we then have to ask: is it really likely that that's happened with of ...

Unknown Cause. It is more than coincidence, says Arp in an article in Science, that so many of the quasars and radio galaxies appear to lie so close to the peculiar galaxies in the sky. The ...
