Edwin hubble brief biography of princess diana family

Hubble's revolutionary work includes finding a constant relationship between galaxies' redshift and distance, which helped to eventually prove that the universe is expanding.

Edward John Spencer, Viscount Althorp, heir to the 7th Earl Spencer, and his first wife, Frances Ruth Burke Roche, had three children, the youngest of whom was her.

Additionally, a classification system that he created for galaxies has been used by other researchers for decades, now known as the Hubble sequence. In , when he was 10 years old, Hubble and his seven siblings moved with their parents to Chicago, Illinois. There, Hubble attended high school and excelled at sports, particularly track and field—as a high school student, he broke the Illinois state high jump record.

Hubble received a scholarship to attend the University of Chicago in While there, he worked as a lab assistant under Robert Millikan, who later won a Nobel Prize for his work in the field of physics. After graduating in , Hubble left Chicago and enrolled at the University of Oxford, where he studied law philosophy. He graduated from the school three years later, obtaining a bachelor's degree in jurisprudence.

Around the same time, Hubble's father, John Hubble, died. After a short stint teaching in Indiana, Hubble returned to the University of Chicago to study astronomy.

Not long after, he was recruited by California's Mount Wilson Observatory to help complete the construction of its Hooker telescope. Before beginning the new position — which he excitedly accepted — Hubble completed a doctorate in astronomy, enlisted in the U. Army and served a tour of duty in World War I. While working at Mount Wilson, Hubble proved that other galaxies existed outside of the Milky Way, where Earth is located, by taking photos through the observatory's Hooker telescope and comparing the varying degrees of luminosity among Cepheid variable stars.

There had been no clear idea of the Milky Way's size at the time, and through his research, Hubble was able to estimate that the Andromeda Nebula thought of simply as a spiral at the time was nearly , light years away from the Milky Way, thus it had to be its own galaxy. The Andromeda Nebula was later proven to be much farther away, at nearly 2.
