TAILIEUCHUNG - Portals to the Universe: The NASA Astronomy Science Centers

The field of astronomy and astrophysics has advanced significantly with the advent of orbiting observatories. The ability to observe unobstructed by Earth’s atmosphere has opened new spectral windows and provided clearer, deeper views of the universe. Working with powerful new ground-based tools, astronomers and astrophysicists have revolutionized our understanding of the universe and the physical laws that govern its existence. | PORTALS TO THE UNIVERSE The NASA Astronomy Science Centers Committee on NASA Astronomy Science Centers Space Studies Board Division on Engineering and Physical Sciences NATIONAL RESEARCH COUNCIL OF THE NATIONAL ACADEMIES THE NATIONAL ACADEMIES PRESS Washington .
