Black holes swoop around one another in a slow, elegant dance, their orbits mo—THWUP! *belching noise*
EDIT: This post originally went up with the wrong images. Sorry about that.
This is not a photograph.
But it's still amazing.
An important thing to remember about science is that some of the stuff we talk about in the general public as "fact" — like, say, black holes — haven't actually been seen by anybody. Instead, black holes exist on paper, as part of theoretical astrophysics. They also exist in indirect evidence — we can look for things in the universe that should exist in a certain way, in a certain place, if our theoretical astrophysics is correct. So far, that lines up, too.
And then there's this thing. Like I say, it's not a photo. It's more like a model. Telescopes — the kind we point at deep space — don't collect images, they collect information. This is a digital rendering made based on information collected when researchers pointed four different telescopes at a galaxy called (poetically) galaxy M87. What you're looking at is a series of simulations, over time, showing massive ribbons of gas undulating and spinning around the something at the galaxy's center. If the theoretical astrophysics is right, this is the closest we've ever gotten to seeing a black hole. Read the rest
