Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to use various indirect methods; one of the most important examines Type Ia supernovae, and this is where the NASA/ESA Hubble Space Telescope excels.
