Image Description: here shows a fictional Exoplanet. The unusual cloud formation is caused by a nearby black hole emitting swallowed spinning light from it's core to the planet's atmosphere as you can see on the image and making the clouds spin in a unique way.

...but black holes don't emit things, do they? Due to their gravitational pull, nothing can escape? i could be wrong, but you might want to check that.
