Unmasking Giant Black Holes

From the NASA Swift team, watch full screen 1080p! Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as the most luminous objects in the universe. Thick clouds of dust and gas near the central black hole screens out ultraviolet, optical and low-energy (or soft) X-ray light. Although there are many different types of active galaxy, astronomers explain the different observed properties based on how the galaxy angles into our line of sight. We view the brightest ones nearly face on, but as the angle increases, the surrounding ring of gas and dust absorbs increasing amounts of the black hole's emissions.

SpaceRip, I love your videos. I am only thirteen, but I am deeply interested in space. So many people at my school, even my Science teacher, think that if you only study space, that you are completely ignoring your planet. They think space is boring. But I know you can unlock secrets of the Earth but studying space. Therefore, I spend most of my time watching your videos, learning about space and constellations and the universe. Thank you for posting these.

@Technoid333 I think moving towards the earth wouldnt fast forward what you see. Because as the theory states.. light's speed is already at max. travelling towards it wont make it go faster even on the spaceship's point of view. so time should be the one to give way. or at least that's what I know...

What the hell is a "blazar"?

Great video :).

@Joshlikestoast i have the same story.

"big black hole" "penetrating" "hard" a bit too erotic i think

@Ridleysama no thats the speed like light in mps
