NSF investments in major telescopes and observatories allow us to peer deep into space and far into the past. These large ground-based instruments, observing at various wavelengths, reveal information about the origins of the universe, its natural laws, and the stars, planets, and other objects it contains. They are superb training grounds forĀ future scientists--and they inspire people everywhere to share the excitement of exploring the unknown.
