On January 11, 1672, the Fellows of the British Royal Society were treated to a demonstration of Isaac Newton’s reflecting telescope, which formed images with mirrors rather than with the lenses ...

Newton used a concave spherical mirror to make his reflecting telescope, a design that is still popular with amateur astronomers due to its simplicity, low cost and high degree of image quality ...

The model itself employs a 4.5-inch main parabolic mirror set in an open ribbed cage. The equatorial mounting has a spring wound drive. According to its donor it was constructed between 1913 and 1915 ...

The Giant Magellan Telescope’s third primary mirror will be unveiled at the University of Arizona’s Steward Observatory Mirror Lab on December 6, 2013 ...

These mirrors, which could be scaled up to the sizes needed in space telescopes, were created by using chemical vapor deposition to grow membrane mirrors on a rotating liquid inside a vacuum chamber.

Super-thin ‘mirror membranes’ could lead the way to bigger space telescopes The lightweight, flexible material could one day produce telescope mirrors even larger than JWST's. By Andrew Paul ...
