Tell me something I don't know, preferably about astronomy. : )

I don't want mathematical gibberish that I cannot understand, just a fun fact or something of that nature. Good luck!

There's recent research that shows that black holes actually emit gamma rays as well as radio bursts. The concurrence of the waves can help identify black holes.

"The team has concluded that the region of the jet closest to the black hole is undoubtedly the place where the gamma-ray and the radio bursts of light originate in about the same time. However, some parts of the puzzle have yet to be resolved, they say: some bright gamma-ray sources in the sky appear to have no radio or optical counterpart — their nature is still completely unknown. "

This is actually quite cool because it takes us one step closer to figuring out black holes.
