Sir Arthur Eddington publishes The Expanding Universe: Astronomy's 'Great Debate', 1900–1931 in Cambridge. Comedian Will Hay observes the periodic Great White Spot on Saturn from his private observatory in London. [1] Fritz Zwicky postulates the existence of dark matter. [2]
They are the first evidence of the center of the Milky Way, and the firsts experiences that founded the discipline of radio astronomy. 1933 – Edward Milne names and formalizes the cosmological principle. 1933 – Fritz Zwicky shows that the Coma cluster of galaxies contains large amounts of dark matter. This result agrees with modern ...
The Cosmic Background Explorer satellite produces a detailed map of the background radiation remaining from the Big Bang. The map shows "ripples", caused by slight variations in the density of the early universe – the seeds of galaxies and galaxy clusters. The 10-meter Keck telescope on Mauna Kea, Hawaii, is completed. The first revolutionary ...
Radio astronomy is a subfield of astronomy that studies celestial objects at radio frequencies. The first detection of radio waves from an astronomical object was in 1933, when Karl Jansky at Bell Telephone Laboratories reported radiation coming from the Milky Way .

The Northern Hemisphere page from Johann Bayer's 1661 edition of Uranometria - the first atlas to have star charts covering the entire celestial sphere Southern Hemisphere. The history of astronomy focuses on the contributions civilizations have made to further their understanding of the universe beyond earth's atmosphere. [1]
By historical astronomy we include the history of astronomy; what has come to be known as archaeoastronomy; and the application of historical records to modern astrophysical problems." Historical and ancient observations are used to track theoretically long term trends, such as eclipse patterns and the velocity of nebular clouds.
An annular solar eclipse occurred at the Moon's ascending node of orbit on Friday, February 24, 1933, [1] with a magnitude of 0.9841. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.
