The Color of Jupiter's Red Storm
First discovered around the mid-1800s, the giant red spot south of Jupiter's equator has been a matter of discussion amongst astronomers. While it's known as being an observable anticyclonic storm the size of two or three Earths possibly caused by the formation of eddies, there are still a few mysteries surrounding the planet's mobile red spot. First, while it's theorized to be caused by organic molecules, why the spot is red is still a real mystery. Other theories point to a reaction between chemicals within the atmosphere or a possible reaction between the colorless ammonium hydrosulfide layer and the cosmic rays from the sun.
