technology has transformed how we explore the Universe. Telescopes,
photography, and spectroscopy remain our basic tools, but
digital light detectors and processors have enhanced their
power. Observatories in space have broadened the range of
light we can gather. Our view of the Universe now extends
from radio waves to gamma rays. And new technologies are revolutionizing
ground-based astronomy, enabling us to create larger and more
powerful telescopes than ever before.
