Today marks the 20th anniversary of the Hubble Space Telescope whose operation has granted us a greater view of our own solar system and distant galaxies formed shortly after the birth of the Universe. Hubble has helped prove and advance different theories for astronomy and physics and has outlived its original projected life span, allowing us to glimpse and understand our place in the cosmos and the life and structure of the Universe. If you would like to learn more about this amazing telescope and see some of the images that it has provided, you can do so through books and websites.
