Astronomers have measured supersonic jet winds on WASP-127b, a giant gas planet located about 520 light-years from Earth. It is the fastest jetstream of its kind ever measured in the Universe, with speeds up to 9 km per second. The team mapped the weather of WASP-127b using the CRIRES+ instrument on the European Southern Observatory’s Very Large Telescope (ESO’s VLT).
