Edwin Hubble
An American astronomer known as Edwin Hubble became a student of astrophysics at Oxford university. Hubble attended Oxford for 3 years to study philosophy, which allowed him to acquire a bachelor's degree in jurisprudence. His contributions towards the astrophysics field include his proof of the expanding universe as well as his creation of a classification system used to determine the different types of galaxies. His discoveries of countless galaxies beyond the Milky Way revolutionised our perception of the universe that we live in. In 1990, a telescope was launched into the Earth's low orbit known as the ‘Hubble Space Telescope’, which was named after Edwin Hubble himself.
