October 2015: Picture of the Month

This is one of the two global maps of Jupiter captured on January 19, by observing the ten hours rotation of the giant gas planet with the Hubble Space Telescope. The all-planet projection represents the first of a series of planned annual portraits by the Outer Planet Atmospheres Legacy program. An interesting feature in the picture: the Great Red Spot, the famous long-lived storm with the wind speed of 300 miles per hour, seems to be decreasing in size (if you compare the original two pictures which can be viewed by going to the APOD site below), although it is still large compared to planet Earth.
