Extreme supersonic winds measured on planet outside our Solar System

Astronomers have discovered extremely powerful winds pummeling the equator of WASP-127b, a giant exoplanet. Reaching speeds up to 33 000 km/h, the winds make up the fastest jetstream of its kind ever measured on a planet. The discovery was made using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile and provides unique insights into the weather patterns of a distant world.
