These supermassive entities are known as high-energy quasars. These are a type of black hole, found in young galaxies, that are surrounded by a thick halo of gas and dust, which produces X-rays as it is sucked into the void. The presence of X-rays, even when the quasars themselves cannot be seen, is what tipped off the scientists to the fact they had stumbled across something extraordinary... The newfound quasars will help answer fundamental questions about how massive galaxies evolve. Astronomers now know, for example, that most of these galaxies steadily generate stars and black holes simultaneously until the latter become too big and impede star formation. The observations also suggest that collisions between galaxies may not, as once thought, play a critical role in galaxy evolution... Two telescopes were needed to see the black holes. One is NASA's Spitzer space telescope, which picks up infrared light, and the other is the Chandra telescope, which relays X-ray data.

This artist's impression shows the thick dust torus that astronomers believe surrounds many supermassive black holes and their accretion discs. When the torus is seen edge-on as in this case, much of the light and radiation emitted by the accretion disc is blocked, creating a "hidden" black hole. [ESA]

Thanks for the ping. bmflr.
gosh, is there anything in the universe that doesn’t look like a giant doughnut?
Daffy and Marvin blew the moon into a cresent shape.
i don’t know. something about space, everything looks like a donut.
i wonder what that says about me?
yeah, but daffy had a donut on his hat, marvin had a donut around his waist, flew around in a donut shaped ship...
and the moon looked like a half eaten donut. :)
I tried...
My Uranium Q-36 Explosive Space Modulator does not make jelly filled.
how did you get yours to convert to uranium? i thought they could only use illudium.
K-9 discombobulated it.
Wouldn’t want to fly to close to one of these.
