Answer:
It turns out that a star's color spectrum is a good indication of its actual brightness. ... By knowing the actual brightness and comparing it to the apparent brightness seen from Earth (that is, by looking at how dim the star has become once its light reaches Earth), they can determine the distance to the star.
