No one knew the Milky Way's size at the time, but because of his research, Hubble was able to estimate that Andromeda Nebula thought as a spiral at the time was nearly 900,000 light years away from us, thus it had to be its own galaxy. Andromeda Nebula was later proven to be nearly 2.48 million light years. The Andromeda Nebula was later renamed the Andromeda Galaxy. In the early 1920s, Edwin began conducting new research, along with fellow friend Milton Humason, on the galaxies' spectral and distances, particularly looking at their connection with the earth. They then published their findings in 1929, theorizing that in galaxies light emissions can show that they are moving away from each other move at a constant rate. In other words, Hubble was stating that a galaxy's redshift is almost twice the size as another's when it's almost twice as far from another galaxy. The men's research was widely
