Reflectors of the World

The First Reflector First reflector designed by Isaac Newton in 1668

1908: Mt. Wilson 60-inch Telescope Los Angeles California

1917: Mt. Wilson 100-inch telescope

1948: Hale 200-inch (5 m) telescope

Square nebula found with Hale

Hubble Space Telescope, 1990

Hubble Space Telescope 2.4 m mirror Not the largest scope, even when it was built in 1990, but easily one of the most important due to its location… in space!

Keck & Keck 2 Hawaii, m mirrors made by 36 hexagon segments in a honeycomb. Largest optical telescope in the world.

Keck & Keck 2 Hawaii, m mirrors in two combined scopes.

Wavelengths of light

Very Large Array (VLA) Radio Telescope, 1980

Our Galaxy in Radio

Chandra X-Ray Telescope, 1999
