Science glossary film: Astronomy

The branch of science that studies the physical universe beyond Earth's atmosphere. It is probably the oldest scientific discipline. Prehistoric civilisations have left behind artefacts that clearly demonstrate some astronomical knowledge, and methodical observations of the night sky were made by early civilisations in China, the Americas, central Asia and Africa.
