Jupiter's Great Red Spot

JUPITER'S AURORA

Adding further to The Aurora Borealis or the Northern Lights spectacular light show on the planet earth which is visible from Alaska, Canada and Greenland, theHubble telescope recently captured brilliant blue auroras on Jupiter’s atmosphere. The Hubble Telescope took images of fluorescent blue lights shimmering on Jupiter’s poles, known as auroras.

Jupiter, the largest planet in the solar system, is best known for its colorful storms, the most famous being the Great Red Spot. Now astronomers have focused on another beautiful feature of the planet, using the ultraviolet capabilities of NASA's Hubble Space Telescope.

These extraordinary vivid glows shown in the new observations are known as auroras that are similar to Aurora Borealis. They are created when high-energy particles enter a planet's atmosphere near its magnetic poles and collide with atoms of gas. Not only are the auroras huge in size, they are also hundreds of times more energetic than auroras on Earth. Unlike those on Earth, these never cease. 

While on Earth the most intense auroras are caused by solar storms - when charged particles rain down on the upper atmosphere, excite gases, and cause them to glow red, green, and purple — Jupiter's auroras are caused by strong magnetic field of the gas that grabs charged particles from its surroundings. This includes not only the charged particles within the solar wind, but also the particles thrown into space by its orbiting moon (Jupiter is known to have the largest number of moons, 67) known for its numerous and giant volcanoes.
