Visions of the Universe: Four Centuries of Discovery DLESE Reviewed Collection
This exhibit uses text and images to portray human views of the universe, and how they have evolved over time. In recognition of the International Year of Astronomy, the exhibit includes six two-sided panels that feature key astronomical discoveries from the past 400 years. The exhibit also highlights the technological advancements that made these discoveries possible. For example, in turning his telescope to the heavens in 1609, Galileo embarked upon a journey that would revolutionize science and culture alike, profoundly changing our view of our place in the universe. Exhibit topics range from celestial objects within our own ?cosmic backyard? to those beyond the realm of our solar system. Featured objects include the Sun, the Moon, Saturn, Mars, comets, stars, nebulae, and galaxies. Images are accompanied by captions that highlight relevant, historical discoveries. The exhibit is supported by supplemental resource documents available online, in PDF format, for each panel. These twelve documents include science background information in the form of Q&As, related science misconceptions, a glossary, and links to additional resources on NASA?s Amazing Space Web site. In addition, each exhibit panel is available as a downloadable, poster-size file.
