Galileo invented a telescope that used curved mirrors rather then lenses.

when a telescope is used for the first time the image it makes is called first light this effect is called refraction the lenses in a telescope are shaped so that they refract light. the first telescopes that were made were sold as toys.Galileo was a famous mathematician who lived between 1564 and 1642.

In those days,mirrors were made of special type of copper that had to be polished every few day.

In 1990, the Hubble space telescope, with its 2.5-metre mirror, was launched into orbit 600 kilometres above earth surface.

In 1990, The Hubble Space telescope with its 2.5-metre mirror was launched into orbit 600 kilometres above earth's surface, well beyond the atmosphere.

1 strange and beautiful things about looking through a telescope is that, as you look into the distance, you are also looking back in time!

Galileo Galilei realised that if he used the telescope in the times of war you could see your enemies before they could see you

If a star is 500 light years away it's light has taken 500 years to reach us

first light came from early telescopes that consisted of two glass lenses in a tube.

The longer the telescope the clearer the image

Over the years there have been many improvements ,for example combining differently shaped lenses using different sorts of glass and combining mirrors and lenses.

One lens was concave(curved inwards on both sides)the other was convex(curved outwards on both sides).light rays that travel through a curved lens change direction.
