June 24, 2019 - Telescope Visionary

Telescope Visionary  Lyman Spitzer, Jr., a world-renowned theoretical astrophysicist, developed the concept of a telescope in space. In 1946—eleven years before the Space Age began—Spitzer proposed the development of a large, space-based observatory that would not be hindered by Earth’s atmospheric distortion and would be able to observe a broad range of wavelengths. This lofty vision ultimately became the Hubble Space Telescope. Spitzer, born 105 years ago this week, researched star formation and plasma physics. He died in 1997 and was honored in 2003 by having the orbiting Space Infrared Telescope Facility renamed in his honor. This Spitzer Space Telescope image of the “Mountains of Creation” shows towering pillars of dust that are aglow with the light of embryonic stars within.
