Auroras on Jupiter

The Auroras on Jupiter can only be seen from the Hubble Space telescope. Jupiter's auroras are hundreds of times more energetic than the ones on earth. They also never end unlike Earth's counterpart that's because they have two sources of energy. One is the solar wind just like Earth's auroras. Another to quote Ashley Morrow from a NASA article “The strong magnetic field of the gas giant 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 Lo, known for its numerous and large volcanoes”. Since Jupiter's atmosphere is mostly helium and hydrogen the most common color of aurora's is blue.
