What did Hubble point out in 1925?
Who Figured This Out? The American astronomer Edwin Hubble made the observations in 1925, proving that there is a direct relationship between the speeds of distant galaxies and their distances from Earth.
How has Ptolemy’s theory been disproved today?
Galileo disproved Ptolemy’s model while using his telescope to investigate the planets. During his observations he discovered that the planet Venus goes through phases, just like our moon, which causes it to appear to change shape. Galileo realised that this would not be possible under the Ptolemaic system.
What are some fun facts about Ptolemy?
He lived from about 85 to 165 A.D. He is famous for his work on astronomy and geography. Very little is known about his personal life. He was an astronomer, mathematician, and geographer. He described in his writing the Greek or geocentric view of the universe.
What year did rheticus contribute to astronomy?
In 1540 Rheticus published his own first account (Narratio prima) of Copernicus’s cosmology, according to which earth is a planet rotating on its axis and revolving annually about a central sun. He later delivered Copernicus’s manuscript of De revolutionibus to Nuremberg, where it was published in 1543.
