The red shift indicates a change in the electronic structure or optical properties of the material.

Since 2009, Riess and his colleagues have used various telescopes to create an elaborate “distance ladder” of the distances and red shifts of nearby galaxies.

Even after adjusting the diopter, white text on the outer edges of the EVF has green and red shifts that I never got used to.

It might even be able to spot some of the stars at a red shift between 10 and 20, corresponding to a period between 100 million and 500 million years after the Big Bang.

“You will see a red shift to some of these numbers on Election Day. Then you will get the aftercount.”
