Lightning Appreciation Post:

There are nearly 500 lightning strikes every second around the world.

Only about 100 of these strike the earth, the others are between and within the clouds themselves.

Lightning is very visible from space (last gif from Astronaut Reid Wiseman)

Besides regular storms (thunder storms, hurricanes, etc.) lightning can be found in volcanoes (gif 3) and even intense forest fires.

In conclusion: nature is fucking awesome!
