astronomy n
The science of the heavenly bodies.
Despite the woefully inadequate weather conditions, Aberdeen has had two observatories. The Castle Hill observatory operated in the 1780s. It was owned by Marischal College and used to teach astronomy and navigation. Later, King's College established the Cromwell Tower Observatory in the 1860s which was used for astronomy and became part of the first national network of meteorological observation stations. Renowned astronomer David Gill started his career at this observatory.
