APOD 4.2

THIS IS SO COOL. I realize that it's only an artist's rendition, because we have never actually been on Titan's surface, but this image of it is so neat. I chose this picture because it's so neat to think that there's weather on other planets/moons, not just Earth. However, there are major differences, obviously, between our storms and theirs. Since the temperature of Titan is consistently about -290 degrees Farenheit, the storms, cycle of evaporation, cloud formation, and rain, is not water but liquid methane. Thunderstorms like this are seasonal on Titan's surface, more along the equatorial regions. However, the lightning drawn in this picture is not confirmed, just theorized. It is thought that it could exist due to the thick, nitrogen-rich atmosphere.
