The Spitzer space telescope not only changed the era of observational astronomy but also brought up a revolution in the field of science. The universe constantly emits bundles of information most of which we fail to understand and receive. In space any particle having a temperature of above zero kelvin (-459.67 degrees F to -273.15 degrees C) radiates out as infrared and could not be deciphered by us, as we lacked resources to detect these radiation. Having Spitzer telescope proved to be an advantage to modern science. “Spitzer’s highly sensitive instruments allow scientists to peer into cosmic regions that are hidden from optical telescopes, including dusty stellar nurseries, the centers of galaxies, and newly forming planetary systems,” NASA wrote on the Spitzer website.
“In its 15 years of operations, Spitzer has opened our eyes to new ways of viewing the universe,” said Paul Hertz, director of the Astrophysics Division at NASA Headquarters in Washington. Spitzer followed a heliocentric orbit rather than a geocentric orbit, trailing away from the orbit of the Earth into space. The satellite consists of a reflector telescope having the diameter of 85 centimeters, made out of beryllium. The Spitzer telescope constitutes of three instruments to perform photometry, spectrometry, and spectrophotometry. Spitzer’s primary mission lasted 5.5 years after which NASA decided to shut it down in 2020. The spritzer space telescope had profoundly made numerous discoveries in the field of astronomy. It was the first observatory to detect direct light coming from exoplanets, it also made its contribution in finding out the new rings of Saturn and found out the planets of Trappist 1 system. Though it was decided that the telescope would be working for 2.5 years only but it worked enormously till 17 years of which the replacement will be the James Webb telescope yet to be launched in the year 2021.
