n turning his telescope to the heavens in 1609, Galileo embarked upon a journey that would revolutionize science and culture, profoundly altering our view of our place in the universe. Our changing views of the universe are portrayed in the images and text of the exhibit, “Visions of the Universe: Four Centuries of Discovery.”
In celebration of the International Year of Astronomy, the exhibit includes twelve panels that feature key astronomical discoveries from the past 400 years. The exhibit also highlights the technological advancements that made these discoveries possible. Exhibit topics range from celestial objects within our own “cosmic backyard” — the Sun, the Moon, Mars, and Saturn — to those beyond the realm of our solar system — including comets, stars, nebulae, and galaxies.
The “Visions of the Universe” exhibit is supported by supplemental resource documents available in these Web pages.
“Visions of the Universe: Four Centuries of Discovery” was produced in December 2008 by the Space Telescope Science Institute, the American Library Association, and the Smithsonian Astrophysical Observatory, through funding from the National Aeronautics and Space Administration.
