EVERYDAY SCIENCE

Detailed explanation-1: -Born in 1933 in Mobile, Ala., Low graduated with a bachelor’s degree in physics from Yale University and earned a doctorate at Rice University in 1959. As a young physicist at Texas Instruments, Low invented the gallium-doped germanium bolometer that initiated the era of thermal infrared astronomy.

Detailed explanation-2: -Between 1959 and 1961, Harold Johnson created near-infrared photometers which allowed scientists to measure thousands of stars. In 1961, Frank Low invented the first germanium bolometer. This invention, cooled by liquid helium, led the way for current infrared telescope development.

Detailed explanation-3: -The huge success of IRAS paved the way for ESA’s Infrared Space Observatory (ISO). Launched in 1995, it was the world’s first general-purpose infrared space observatory, which operated until 1998. NASA’s Spitzer Space Telescope concluded its 16+ year mission in 2020.

Detailed explanation-4: -infrared telescope, instrument designed to detect and resolve infrared radiation from sources outside Earth’s atmosphere such as nebulae, young stars, and gas and dust in other galaxies.
