It was on 24th April 1990 when one of the most defining steps about the human being's age-long curiosity for the universe was taken. When the clock struck 15:33, the Hubble Space Telescope, taking its name from Edwin Hubble, was carried into its orbit around Earth by the spacecraft Discovery on its STS-31 mission. Hubble observed more than 1 million celestial bodies during its time in the orbit. In light of the newly acquired data, 13.000 academic articles were published and these articles were referenced more than 550.000 times.
