The black hole is seen nearly edgewise in this new visualization from NASA. The turbulent disk of gas around the hole takes on a double-humped appearance. The hole’s extreme gravity alters the paths of light coming from different parts of the disk, producing the warped image. "What we see depends on our viewing angle," NASA said.

NASA released this new new visualization of a black hole this week, generated by astrophysicist Jeremy Schnittman at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Schnittman's areas of expertise include the computational modeling of black hole accretion flows. That's what you're seeing in this visualization: the flow of material around a black hole as it might appear if you could see the hole up close (but not too close!), and from the side.

Take one minute to watch a video of a system of 3 galaxies, all orbiting each other, about a billion light years from Earth. Each galaxy contains a supermassive black hole. The black holes are circling each other and about to collide. Read more and watch.
This article is from the Post's Capital Weather Gang, a source we trust. Here, they're talking about 1) 'unprecedented' changes in the oceans, 2) the possibility that 100-year floods will become annual events and 3) Earth's quickly melting permafrost. Read more.
What could be better than a beautiful night under the Milky Way? When you look up, every individual star you can see with the eye - in all parts of the sky - lies within the confines of our galaxy. Read more.This image is via Ben Coffman Photography in Oregon. Thank you, Ben!
