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

- 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
