For the past 40 years, scientists have been using infrared space telescopes to study the universe, including NASA missions such as the Infrared Astronomy Satellite (IRAS) launched in 1983, the Spitzer Space Telescope launched in 2003, and the James Webb Space Telescope launched in 2021. Although the Webb Telescope has opened a new window to the universe, it builds on missions from 40 years ago, including Spitzer and the Infrared Astronomy Satellite. The James Webb Space Telescope is the largest and most powerful space observatory in history, celebrating its second anniversary since its launch. Its clarity of images has inspired the world, and scientists are just beginning to study its scientific benefits.
The success of Webb builds on four decades of work with space telescopes that also detect infrared light. Telescopes such as the IRAS and the Spitzer Space Telescope provide crucial insights into star formation, cosmic gas and dust clouds, and the existence of exoplanets. These telescopes have contributed to groundbreaking discoveries about the universe and have paved the way for future infrared missions, such as NASA’s upcoming SPHEREx and Nancy Grace Roman Space Telescope.
The legacy of these infrared space telescopes is reflected in the images of star-forming regions, such as Rho Ophiuchus and Fomalhaut, which have revealed previously hidden features and provided insight into the formation of stars and planets. Infrared light has become an essential tool for understanding the universe on various scales, from the study of galaxy evolution to the detection of exoplanets and the investigation of dark energy.
The Webb Telescope is paving the way for complex and diverse scientific questions by building upon the knowledge gained from previous infrared telescopes such as IRAS and Spitzer. Its success is fueling the anticipation of future infrared missions that will continue to expand our understanding of the universe.
