In Jupiter's North Equatorial Belt, scientists spotted a rare wave that had been seen there only once before. It is similar to a wave that sometimes occurs in Earth's atmosphere when cyclones are forming. This false-color close-up of Jupiter shows cyclones (arrows) and the wave (vertical lines).

Hubble's Wide Field and Planetary Camera 3 (WFPC3) was developed jointly by NASA's Goddard Space Flight Center, Greenbelt, Maryland; the Space Telescope Science Institute, Baltimore, Maryland; and Ball Aerospace & Technologies Corporation, Boulder, Colorado.
