Edwin Hubble was born in Marshfield Missouri in 1889. ... In Hubble’s time, the center of
obersevational work on the new astrophysics, and later on what we know as cosmology
was the Mount Wilson observatory. ... Hubble had continuing access to both the 60 inch and the 100 inch hooker
reflectors. ... In the early 1920s Hubble played a key role in
establishing just what galaxies are. ... In the 1924s Hubble measured the
distant to the Andromeda nebula, a faint patch of light with about the same apparent
diameter as the moon, and showed it was about a hundred thousand times as far away as
the nearest stars Hubble was able to measure the distances to only a handful to other
galaxies, but he realized that as a brightness as an indication of their distance. ... The observational data available to Hubble by 1929
was sketchy, but whether guided by inspired instinct or outrageous good fortune, he
correctly divined a straight line fit between the data points showing the red shift was
proportional to the distance.
