Supersonic Jet Streams Discovered on Exoplanet WASP-127b

Astronomers using the European Southern Observatory's Very Large Telescope (VLT) have discovered supersonic jet streams on WASP-127b, a giant exoplanet 520 light-years from Earth. These winds, reaching speeds up to 33,000 km/h, are the fastest ever measured on a planet. The discovery, detailed in Astronomy & Astrophysics, provides unprecedented insights into the weather patterns of distant worlds. Analysis using the CRIRES+ instrument revealed water vapor and carbon monoxide in WASP-127b's atmosphere, along with temperature differences between poles and equator, and even between morning and evening sides. This complexity mirrors weather patterns in our own solar system. Future observations with ESO's Extremely Large Telescope promise even greater detail.
