A collaboration of NASA, ESA, and the Canadian Space Agency (CSA), the James Webb Space Telescope is an advanced space-based reflecting telescope with a 6.5-meter diameter segmented mirror.

A short history of Sir Isaac Newton, the mathematician and physicist that helped invent and explain some of the most fundamental laws of science.

Astronomers have constructed telescopes of every kind - massive observatories designed to pick up faint traces of light across space.

Within sixty years, Isaac Newton had built his own new and improved reflecting telescope with a curved mirror, coated with a fine layer of reflective silver metal, instead of lenses.

Newton discovered calculus, created the first reflecting telescope, and established the laws of gravity, amongst many other scientific feats. But he also was a complete ass.
