Start your study of astronomy by reviewing the accomplishments of the very first astronomers, and then continue looking at important historical markers of the Space Age.A celestial timelinePeople have been fascinated with the stars and planets since ancient times.

The Roswell Incident is the most famous UFO story on record and is the cornerstone of an alleged government conspiracy to hide alien visits from the world.
