the boundlessness of space and the universe, we are immediately filled
with curiosity about our own origins and wonder about the objects, life
forms, and matter that populate the cosmos. Through the observations and
work of astronomers over time, we have slowly been able to reduce the
number of unknowns and develop explanations or theories for some of the
celestial objects and phenomena we see. This space-traveling survey
recounts some of the major discovery milestones in the field of
astronomy and examines the tools and techniques currently used by
astronomers to study the universe.
