Astrophysicist Paul Westoby and colleagues from Liverpool John Moores University in the U.K. used data from the Sloan Digital Sky Survey to survey spectral lines from 360,000 relatively nearby galaxies.
Redshift of the spectral lines in the light from a galaxy reflects its velocity relative to our galaxy.
