NASA's Hubble Space Telescope captured Jupiter's ever-changing weather.
Jupiter has many huge cyclones, notably the Great Red Spot, which is broader than Earth.
Hubble's January images show Jupiter's shifting weather on both sides.
Project Outer Planet Atmospheres Legacy (OPAL) photographs.
OPAL observations of Jupiter, Saturn, Neptune, and Uranus by Hubble occur annually.
The left image shows the Great Red Spot and Red Spot Jr. on the lower right.
The opposing spinning storms should pass each other every two years.
NASA says storms merging between 1998 and 2000 created the smaller structure.
