  1. Similar to the "Great Red Spot" on the planet Jupiter, scientists have nicknamed a large dusty-black ink-spot on Neptune the "Great Dark Spot." Images from the spacecraft Voyager show that the Great Dark Spot is located around Neptune's mid-section. What they have discovered is that this area is actually a storm with tempestuous winds raging at a staggering speed of 500 miles per hour (805 kilometers per hour). This isn't surprising, really, since the winds on Neptune are the fastest winds in our entire solar system.
