All The Best Images From NASA's Black Hole Friday - In a proud and noble tradition stretching back a whole two years, NASA yesterday did Black Hole Friday, rather than just flogging a few Apollo mini-figs for 25 percent off. We got science, we got knowledge, and of course, a bunch of jaw-dropping images of black holes. Here are the best.
Grim Reapers Black holes are so dense that nothing can escape from their gravitational clutches. Once past the event horizon, or the boundary beyond which even light cannot escape, there’s no way out.
