The above simulation represents part of the absorption spectrum from the bright star Vega in the constellation Lyra located about 25 light years from Earth. (The wavelength, in nm, may be obtained by a mouse-down in the spectrum.) For simplicity only the H-alpha line in the Balmer series is shown. In general, there are a lot of stars in our galaxy that are blue-shifted. However, the great majority of galaxies are red-shifted. This leads astronomers to the conclusion that the universe is expanding.
Side note: Since Earth's axis is slowly changing its orientation, Vega will be the North Star in ~ A.D. 14,000!
