Today (January 3, 1906) is the birthday of William Wilson Morgan, the developed the morphological classification systems of galaxies.

Today (January 3, 1906) is the birthday of William Wilson Morgan, the developed the morphological classification systems of galaxies.

William Wilson Morgan was born on January 3, 1906, in the United States. Morgan studied at the University of Washington and the University of Illinois but dropped out in his final year. He began his career as a research assistant at the Yorkshire Observatory. He has also taken classes for students there. The observatory is owned by the University of Chicago. He graduated from the University in 1927 with a Bachelor of Science degree. For this, the two university values he studied and the Yorkshire astronomy subjects were considered. He also continued his postgraduate studies while at the University of Chicago's Jerkess Aeronautics. He received his doctorate in December 1931. After completing his doctorate at the University of Chicago, he joined the University as an Assistant Professor in 1936, a Professor in 1947 and a Qualifying Professor in 1966.

Morgan, along with Philip Childch Keenan, developed the radiation system MK system, which classifies galaxies by radiation. He developed several Milky Way prototype systems. Hubble developed Milky Way systems that used the objective, measurable properties of the Milky Way as an alternative to the desired simple, characteristic, observational values. He developed the now widely used CD classification for supermassive galaxies in the middle of galaxies. In 1970 Ilavura b. In conjunction with Pouches developed the Pouches-Morgan classification for galaxies is still in use today. This time CD galaxy identified itself as one of the most concentrated galaxies.

Morgan Yerkes spent most of his life in the sky. He was also its director from 1960 to 1963. Together with Donald Osterberg and Suttiward Charles, he measured the distances of O and B constellations and established the existence of spirals in our Milky Way galaxy. For some time he was the managing editor of the journal Astronomy. This publication was first started by George Ellery Fale to promote the collaboration of astronomers worldwide. He was head of the Department of Astronomy at the University of Chicago from 1960 to 1966. His primary research topic is galaxy classification. He also helped to establish the formation of coils in our Milky Way galaxy.

In addition to these scientific qualifications, he has been a professor and director of astronomy at the University of Chicago and the managing editor of George L.'s journal of astronomy. He has won the Bruce Medal (1958), the Norris Russell Lecture Certificate (1961), the American Academy of Sciences (1964), the American National Academy of Sciences the Enrique Trapper Medal (1980), and the Erzell Medal (1983). Asteroid 3180 Morgan is named after him. William Wilson Morgan, the inventor of the Milky Way galaxy, passed away in the United States on June 21, 1994, at the age of 88.
