Well, there are several ways. Cepheid variables are often used. Their period of variation is related to their luminosity, and comparing the observed and intrinsic luminosity gives the distance. Also, the Tully-Fisher relation for spiral galaxies and the Fundamental Plane method for elliptical galaxies are employed in distance measurement.

Astronomers also use standard candles like certain types of supernovae. These have known intrinsic brightness, and by comparing their observed brightness, the distance can be estimated. Another approach is based on the redshift of light from distant galaxies. The greater the redshift, the farther away the object is.
