In the past couple of years, a new sibling storm [to Jupiter's Great Red Spot] has erupted. The Little Red Spot, or Red Spot Jr., formed from the merger of three smaller white-colored storms in Jupiter’s southern hemisphere. The Little Red Spot, [at center of this picture], has kept growing since it was discovered in 2006 and is now about the size of Earth—and with wind speeds of 400 mph, it is now spinning as fast as its larger predecessor.
