Discovery of Galaxies Key points: How it was established that other galaxies are island universes of stars; standard candles and distances; the distance ladder While the Milky Way was considered to be a thin, distorted disk of stars with the sun near the center in the early 20th century, other galaxies were confused with gaseous nebulae, and.

This is a radio galaxy. At the time of discovery, quasar Q at z=, discovered in , was the most remote object known. In , quasar PC + was discovered at z=, making it the most remote object known. This was the first galaxy discovered above redshift 3. It was also the first galaxy found above redshift 2.
