  - have an accurate source of one second time pulses
* Most observatories are built on mountaintops where the air is thinner and cleaner
  - open to the outside air
  - have origins
* Observatories also have to be away from places that have lots of light, like cities.
* Observatories are buildings
  - data collecting facilities
  - on mountaintops to get the astronomers closer to the planets and stars
  - temples to science
  - the main centers for preparing astronomical data and performing researches

  - specializing in solar astronomy usually have coronographs and spectroheliographs
  - take many forms
* Some observatories are small, operated by astronomy clubs, and housing modest telescopes
  - have accurate information available on atmospheric pressure
  - use mirrors originally intended for other work - such as solar power studies.
  * An 'observatory' place for making observations. Usually it means a building that holds one or many big telescopes. Observatories are used by astronomers to look at the sky. Observatories are usually high up on mountains or hills, because they need clear and clean air to be able to see properly. The higher you go, the clearer, dryer and cleaner the air gets. Observatories also have to be away from places that have lots of light, like cities. Too much light can make it so that the astronomers cannot see out of the telescope very well
