Today’s Fact : Why astronomers build observatories on mountain top?

Astronomers are scientists who study the heavens. Many of them build their observatories on high mountains from where they can study the stars and planets.

Our planet is surrounded by layers of air which we call the atmosphere. It allows light and some radiation to pass through and protects life on earth. However, the atmosphere contains lots of clouds and dust which do not allow all radiation form sun and stars to pass.

Astronomers obviously wish to obtain the clearest view of the stars. By building their observatories on high mountains, there are fewer layers of air above them to block their vision.

Astronomers also use telescopes which are attached to satellites. The satellites orbit the earth above the atmosphere, so that they can send back clear pictures.
