Telescopes

Telescopes are astronomy's most important tool. Without them our picture of the Universe would be dramatically less rich and detailed.

There are many different types of telescope. Traditional ones gather visible light from distant objects to produce a magnified image. It was this kind of instrument that was first pointed skywards by the Englishman Thomas Harriot and later put to famous use by Galileo Galilei.
