In the old days, many believe that we are the only living things on our galaxy or even in the whole universe. No one even bothers to look beyond our planet and explore the space for that matter. Though in Ancient Egypt, Babylonians use to study the Sun, Moon and stars just to generate a calendar for farming and religious rites but it never extended that far.
Then in early 1900's people started to explore space and study matters beyond our planet. Edwin Hubble was the first person who introduced us to the cosmos such as the galaxy and the universe. Hubble altered our thinking of outer space and because of that a space telescope was launched in Earth's orbit in recognition of him and called the Hubble Space Telescope.
