- Question 1:
- What is Jupiter's Great Red Spot?
Jupiter's red spot is the most noticeable feature on the planet. It is a giant, spinning storm that has been raging for at least a hundred years — perhaps since telescopes were first used to study celestial objects. Scientists have marveled at the storm's ability to survive, but they believe the spot is now shrinking. The storm has winds that reach up to 400 miles an hour (640 kilometers an hour). The red spot shares some characteristics with Earth's hurricanes. Scientists do not know why the spot is red. A leading theory is that the material being pulled upward from deep inside Jupiter's atmosphere turns red when sunlight strikes it.
