Meet Jupiter’s Great Red Spot! It is a giant, long-lasting swirl in Jupiter’s clouds.

What we learn:
Jupiter is a gas giant with no solid ground
Its air is mostly hydrogen and helium
It spins very fast: one day is about 10 hours
Fast winds make stripes, like lanes on a highway

How the big storm formed:
Warm gas rises; cool gas sinks
Many small storms joined into one big swirl
Jupiter’s quick spin helps the swirl keep turning

Why it lasts so long:
No land or mountains to slow the winds
Warm inside gives the storm energy
It sits between strong wind bands that keep it spinning

Fun facts:
Today it is a little bigger than Earth
The red color may come from chemicals changed by sunlight (scientists are still studying)
People have watched it for at least 300 years
Spacecraft like Voyager and Juno took close-up pictures
It used to be wider and is slowly getting smaller, but it is still huge
