Jetstream winds on the giant gas planet WASP-127b

Artist’s impression of the giant exoplanet WASP-127b orbiting its host star, and the supersonic jet winds that were discovered on the planet. With speeds up to 9 km per second (almost 33 000 km/h), the wind on the planet’s equator is the fastest jetstream of its kind ever measured in the Universe.

Astronomers mapped the weather and make-up of WASP-127b using ESO’s Very Large Telescope (VLT).
