The resolution of this debate came with the detection of novae in the Andromeda galaxy by Edwin Hubble in 1923 and 1924.
Students' forms are split into George Spencer's four houses: Armstrong, Hubble, Loxley and Socrates.
This was one of the most important discoveries in cosmology since Edwin Hubble demonstrated in the 1920s that the universe was expanding.
He has authored or co-authored 15 books on cosmology and astrophysics, and wrote, with Alexander S. Sharov, a biography of Edwin Hubble, E. Hubble, Life and Work (Cambridge University Press 1992).

Bryson tells the story of science through the stories of the people who made the discoveries, such as Edwin Hubble, Isaac Newton, and Albert Einstein.
In the face of the observational evidence for the expansion of the universe obtained by Edwin Hubble in the late 1920s, Lemaître's results were noticed in particular by Arthur Eddington, and in 1930–31 his paper was translated into English and published in the Monthly Notices of the Royal Astronomical Society.
The Andromeda Galaxy, for instance, was referred to as the Andromeda Nebula (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble and others.
However, he took a hiatus from pursuing his advanced degree and went to work as a human computer at the Mount Wilson Observatory from 1929–1931, where he assisted luminaries such as Edwin Hubble, Paul W. Merrill, and Milton L. Humason.
