It's not Sun.
It's the magnetic field of Jupiter.
See, jupiter is a big planet, but looks puny against its magnetic field.
Charged particles in the solar winds stretch the field away from Sun, like a comet's tail.
It stretches 7 million km towards the Sun, and over a billion km in the opposite direction— Saturn orbits inside it sometimes.
If you could see the field from Earth, it would appear 5 times larger than a full moon.
Jupiter's magnetic field is roughly 20,000 times stronger than Earth's. What generates it?
Deep beneath the clouds, the pressure is so high that hydrogen is crushed to a metallic liquid, and conducts electricity.
This conductive ocean rotates around the core at high speeds. It generates electricity like a dynamo.
Jupiter's magnetosphere also creates stunning auroras. They're not larger than earth’s auroras, but larger than Earth.
