A Brief History by Jordan Sibberas

The first recorded telescope was created in the Netherlands by Hans Lippershey, Zacharias Janssen and Jacob Metius in The idea was that mirrors could be used for light-gathering as opposed to lenses. The first practical application for this technology was designed by Isaac Newton in 1668, called the Newtonian Reflector.

A simple Refractor telescope takes light beams and focuses it into a ‘light point’ with a convex lens. Then, a second lens focuses it into an image the size of the eye’s pupil.

Reflector telescopes use the same principal, except with mirrors. The primary mirror at the back reflects a large image onto a smaller secondary mirror, which reflects the image onto a focal point.

Telescopes used to be used for sea exploration and observing far-off objects, but are now used mainly for observing space and the galaxy. They range from small, not-so-powerful telescopes for the casual star observer to the huge Hubble space-telescope, which is used for discovering far-off galaxies and the universe’s secrets.

The future of telescopes lies in the growing number of space telescopes. These are huge, super-powerful telescopes which are sent into space to observe far-off galaxies and distant parts of the universe. They will be used to explore and better understand our universe and to help unravel its mysteries. Artist’s impression of a future telescope.
