Cosmological Distance Ladder
Cosmological Distance Ladder
The cosmic distance ladder refers to the succession of different methods that astronomers use to measure distances to objects in the sky. Some methods, like parallax, work well for only nearby objects. Other methods, like using the cosmological redshift, work only for very distance galaxies.

Distance Computation of Supernovae pdf.pdfSupernovae play a dynamic role in calculating the distance of galaxies from the earth.
Supernova as distance indicator technique has been popular since the past few years. Supernova technology is highly used by the astronomers in solving many problems in cosmology including Hubble Constant and cosmological parameters.
