What is Observatory?
[[File:Griffith Observatory, Los Angeles, California.jpg|thumb|right|Griffith Observatory<br> in Los Angeles, California.]] An '''observatory''' is a place for making [[observation]]s. The term is most used for [[Astronomy|astronomical]] observatories, which are places for looking at the [[sky]]. A modern astronomical observatory has a large [[telescope]], or several. It is usually high up on [[mountain]]s or [[hill]]s, because higher places have cleaner, clearer, dryer air. Observatories also have to be away from places that have lots of [[light pollution]], like cities. Too much light can make it so that the [[astronomer]]<nowiki/>s cannot see out of the telescope very well. {{Commons category|Observatories}} {{tech-stub}} [[Category:Observatories| ]]
