SUMMARY
Astronomers determine the rotation and surface speed of distant stars using the Doppler shift phenomenon. When stars emit light, their motion relative to Earth causes a change in the wavelength of that light, which can be detected as a shift towards the red or blue end of the spectrum. This technique allows for precise measurements of stellar rotation and velocity, despite the stars appearing featureless through telescopes.
