Astronomical research is dependent on technology that allows astronomers to see the universe. Telescopes act as giant eyes, capturing the light from celestial objects and processing it for astronomers to study. Generally, a space-based telescope will offer the clearest views of the universe. However, astronomers have found an ideal site for ground-based telescopes. In this video segment adapted from First Light, learn about recent telescope technologies and one of the best ground locations—Mauna Kea.
