Winds on Venus (EuroVenus Episode 2)
March 04th, 2016
The winds of Venus are being studied through a combination of space-based observations - from the Venus Express orbiter - using observations from a number of telescopes.
This film follows researchers using the Canada-France Hawaii Telescope (CFHT) to measure Venus cloud-top wind speeds by measuring the Doppler shift of sunlight reflected from Venus clouds; these are then compared with wind speed measurements obtained by tracking the motion of clouds from imagery from the Venus Express satellite.
