At the heart of most, if not all, giant galaxies lies a supermassive black hole. When dust and gas falls into the central black hole, it heats up and emits intense radiation. Quasars, some of the brightest objects in the cosmos, are powered by these phenomena. In these artist’s impressions of a quasar, the rotating ring of matter, and powerful jets of particles thrown out at close to the speed of light can be seen.

A wormhole? A GIANT spaceship? An intergalactic disco? None, actually.

This is, believe it or not, a real photo taken by the Chandra x-ray observatory. The central object is a quasar, RX J1131-1231 (RX J1131 for short), located about 6 billion light years from Earth.

According to Chandra, "Gravitational lensing by an intervening elliptical galaxy has created four different images of the quasar, shown by the Chandra data in pink.”

It’s certainly one of the clearest images of this effect we’ve seen in a while, and one of the sparkliest!

NGC 7319 is a galaxy in Pegasus, member of Stephan’s Quintet. Near the nucleus of NGC 7319 a quasar shines brightly. Quasars are generally described as being super luminous galaxies formed during the early universe, but the reason this quasar is so puzzling is that there is very little absorption of its light due to the effect of the gas and dust of NGC 7319. Perhaps, as some astronomers suggest, some quasars are actually the stripped cores of devoured galaxies that have been subsequently spit out by the surviving galaxy such as NGC 7319.

Many other galaxies seem to have a high number of detected quasars near them. This could be an observational bias or perhaps in this case the light of the quasar just happens to shine through a fortuitous window of NGC 7319.

Astronomers have discovered a huge formation of 73 quasars representing the largest structure yet observed in the universe. 

The quasar group is very distant, and therefore existed when the universe was much younger than it is now. A quasar is a very energetic black-hole-powered galactic nucleus. Quasars first appeared in the very early universe, soon after the Big Bang. The light from a quasar is so intense that it can be visible from across the universe.

A remarkable thing about the new discovery is that the structure is larger than cosmological theory says is possible.

The currently accepted Cosmological Principle, based on the work of Albert Einstein, suggests that the largest structures we should be able to find would be about 370 megaparsecs across (more than 1.2 billion light-years). The newly found quasar group is 1,200 megaparsecs across, a distance that would take four billion years to cross at the speed of light.

The largest structures that we know that are close to Earth are super clusters of galaxies surrounding vast voids in space. The Sloan Great Wall is the largest such structure and is at the top end of the size limit set by the Cosmological Principle.

Multi-Telescope View of Giant Black Hole Is 2 Million Times Sharper than Human Eye

Telescopes in Chile, Airzona and Hawaii have captured the best view ever of a giant black hole at the center of a galaxy 5 billion light-years from Earth, an spinning beacon in the night known as a quasar.

I love Phyla-Vell.

I love Guardians of the Galaxy.

Busting my ass to upgrade Quasar is basically the story of my life — full of screaming and crying, caused by the very things I cherish. (And yet here I am, knees deep in planning the next.) But what really overfloweth my heart with big dumb stupid grinning joy, was everybody who helped make the magic happen — with special frantic heart hands to Lionel, who pulled together a last minute light-up sword for this. Yes. That sword? That was all him.

Interplanetary warrior girlfriend high five, y’all.
