What is Astronomy - by Danna Hooker about?
Astronomy is the scientific study of everything beyond Earth, including celestial bodies and the nature of time and space. Ancient civilizations made significant contributions to astronomy by observing the sky for agricultural and calendrical purposes. The universe began with the Big Bang approximately 13.8 billion years ago, and concepts such as multiverses and the light from dead stars further illustrate the vastness and complexity of the cosmos.
