Astronomy Picture of the Day

Explanation: Take this simulated plunge and dive into the upper atmosphere of Jupiter, the Solar System's ruling gas giant. The awesome animation is based on image data from JunoCam, and the microwave radiometer on board the Jupiter-orbiting Juno spacecraft. Your view will start about 3,000 kilometres above the southern Jovian cloud tops, but you can track your progress on the display at the left. As altitude decreases, temperature increases while you dive deeper at the location of Jupiter's famous Great Red Spot. In fact, Juno data indicates the Great Red Spot, the Solar System's largest storm system, penetrates some 300 kilometres into the giant planet's atmosphere. For comparison, the deepest point for planet Earth's oceans is just under 11 kilometres down. Don't panic though, you'll fly back out again.
