Glossary term: Sky Map

Description: A map that points out the location of astronomical objects (stars, planets, the Sun, the Moon, etc.). Large astronomical surveys map the sky to both provide data for astronomical research and to help select targets for large telescopes. Some sky maps make repeated observations of the same part of the sky allowing the scientific studying of the movement of objects across the sky and of the change in brightness of astronomical objects. Interactive sky maps are available as computer programs or mobile apps.
