"New Instrument Gauges Jupiter's Fierce Winds in Exoplanet Research Trial"

Researchers using the ESPRESSO spectrograph on the ESO's Very Large Telescope have successfully measured Jupiter's wind speeds by analyzing the Doppler shift in sunlight reflected by the planet's clouds. This technique, typically used for hunting exoplanets, revealed wind speeds ranging from 37 to 266 mph on Jupiter. The findings enhance our understanding of Jupiter's atmospheric dynamics and could be applied to study other gas giants like Saturn.
