It was discovered that there is a black hole orbiting that black hole. A binary system comprised of black holes! Ridiculous! The black hole orbiting through the accretion disk around the primary black hole was what tipped astronomers off-which is amazing, that they can figure all of this out from so far away. The orbit of the smaller black hole is deteriorating, and it is supposed to merge with the other black hole. But none of us will be around to see it.
And how's this for terrifying!!

The top part is just an artist's rendition. The bottom two pictures though...those are real. That is actual imagery of a star in galaxy RXJ1242-11 being devoured by a black hole! The worst part about it-another star pushed it in. What a jerk.
How about something a little closer to home. Voyager 1 is currently the farthest man made object from home. The little space probe that could keeps on trucking, and has given us some awesome images of our galaxy
