ISO (Infrared Space Observatory)

The Infrared Space Observatory (ISO) was a space telescope launched by the European Space Agency in 1995 to study the universe in infrared light, which is invisible to human eyes. Infrared observations allow scientists to see through dust clouds and observe cool objects like star-forming regions, distant galaxies, and planets. Operating until 1998, ISO provided valuable data on the structure and composition of celestial bodies, advancing our understanding of cosmic processes. Its findings helped expand knowledge of how stars and galaxies form and evolve, making it a significant tool for exploring the universe beyond the capabilities of visible-light telescopes.
