Name: The Sky at Night S24E1 - Mapping the Sky
Uploaded: 1980-01-10
Description: How many people know the meaning of terms such as ' right ascension' and ' declination '? And what exactly is the celestial sphere? Mapping the sky presents problems different from those of mapping the earth. Patrick Moore talks about sky-maps, and how astronomers have worked out their own equivalent of latitude and longitude.
