The Incredible Evolution of NASA’s Infrared Telescopes

NASA has been using infrared space telescopes to study the universe for the past 40 years. These missions include the Infrared Astronomical Satellite (IRAS), launched in 1983, the Spitzer Space Telescope, launched in 2003, and the James Webb Space Telescope, launched in 2021. The James Webb Space Telescope has provided new insights into the universe and builds upon the discoveries made by previous missions such as Spitzer and IRAS. These telescopes have allowed scientists to observe star-forming regions like Rho Ophiuchi and study the evolution of stars and planetary systems. Additionally, they have contributed to the understanding of important astronomical phenomena such as dark energy and the presence of exoplanets. The legacy of these telescopes continues with future missions like SPHEREx and the Nancy Grace Roman Space Telescope, which will further explore the universe using infrared technology.
