    Launched: August 25, 2003

    Overview

    The Spitzer Space Telescope was one of NASA's Great Observatories, designed to observe the universe in infrared light. It played a crucial role in the study of cold objects like dust clouds, cool stars, and molecules in space that are invisible in optical light.

    Primary Objectives

    • Study cooler objects in space like dust clouds and failed stars
    • Observe newly forming planetary systems
    • Look through dust clouds to see hidden objects
    • Study distant galaxies and objects from the early universe

    Notable Discoveries

    • Found the largest known ring around Saturn
    • Made the first observations of light from extrasolar planets
    • Discovered new ring systems around Saturn
    • Identified organic molecules in distant galaxies
