Caption: A collage of a full Jupiter in visible light (true color, but maybe enhanced) and an auroral oval (AKA auroral ring) in ultraviolet (false color, of course).

Features:

1. One can see the dramatic band structure of Jupiter.

2. The Great Red Spot is giant anticyclonic storm. It's longest dimension is about 3 times the Earth's diameter---i.e., ∼ 40,000 kilometres west to east (see Wikipedia: Great Red Spot: Structure).

   The Great Red Spot may have existed in the 17th century, but has certainly been identified and observed continuously since 1830.

3. There are also three obvious white ovals, south of the Great Red Spot, which are smaller anticyclonic storms (Wikipedia: Atmosphere of Jupiter: vortices).

4. The huge nature of Jupiter is a main ingredient in causing weather features to be so enduring by comparison to Earth.???

5. Wikimedia Commons Caption: "2016 Jun30: Astronomers are using NASA's Hubble Space Telescope (HST) to study auroras---stunning light shows in a planetary atmosphere---on the poles of the largest planet in the Solar System, Jupiter. The auroras were photographed during a series of Space Telescope Imaging Spectrograph (STIS) far-ultraviolet observations taking place as NASA's Juno spacecraft approaches and enters into orbit around Jupiter. The aim of the program is to determine how Jupiter's auroras respond to changing conditions in the solar wind, a stream of charged particles (a stream of plasma consisting mostly of electrons, protons, and alpha paricles (He-4 nuclei)) emitted from the Sun. Auroras are formed when charged particles in the space surrounding the planet are accelerated to high energies along the planet's magnetosphere: i.e., the Jovian magnetosphere. When the charged particles hit the Jovian atmosphere near the planetary magnetic poles, they cause it to glow like gases in a fluorescent lamp. The Jovian magnetosphere is 20,000 times stronger than Earth's magnetosphere. These observations will reveal how the Solar System's largest and most powerful magnetosphere behaves."
