A gas giant 520 light-years away has equatorial atmospheric motion approaching 33,000 kilometres per hour—around 16 times Neptune’s fastest winds. When announced in January 2025, it was the fastest planetary jet stream yet measured, although an even - Space Daily

WASP-127b's brief wind-speed record reveals how Doppler-shifted molecules can turn an unresolved exoplanet into the beginnings of a weather map.

For 28 days in early 2025, WASP-127b held one of planetary science’s most striking records. Atmospheric material around the equator of this distant gas giant was inferred to be moving at close to 9 k… [+12791 chars]
