In Earth's upper atmosphere, a fast-moving band of air called the jet stream blows with winds of more than 275 miles (442 km) per hour, but they are not the strongest in our solar system. The comparable high-altitude winds on Neptune reach about 1,

Astronomers have uncovered one of the most extraordinary atmospheric phenomena ever observed on an exoplanet. Using the European Southern Observatory’s (ESO) Very Large Telescope (VLT) in Chile, researchers have measured supersonic winds racing around the equator of the distant gas giant WASP-127b.
