Sometimes on Earth we can see pretty light shows in the sky called the Northern Lights or the Southern Lights。
These light shows are also called the aurora。 Guess what? Earth isn't the only planet with aurora! This picture shows the aurora around the North Pole of the planet Jupiter。
The Hubble Space Telescope took the picture in 1998。 The aurora form a ring or oval around Jupiter's pole。
What makes the aurora? Charged particles zoom along Jupiter's magnetic field lines。 When the particles crash into gases in Jupiter's atmosphere, they give off light。
That light is the aurora!。
