APOD 2.2 (Spicules)

Almost everyone knows what a solar flare is (a large emission of solar radiation that quickly travels away from the Sun), but only a few know what spicules are.  Basically, it is a lot like the "plop" of water that comes up when you drop something circular in from a great height, at which point a circular area of water moves upward with a force equal to that of the object the moment it hit the water, creating a tubular structure that holds it shape until it runs out of energy to rise upward, and it comes crashing down in the exact opposite way it came up.  Now that the image is fresh in your mind, swap out the water for molten-hot magma gas, and you have the image of a spicule.
