Spitzer Space Telescope

Definition

The Spitzer Space Telescope was a space-based observatory launched in 2003, designed to observe the universe in infrared wavelengths. It played a significant role in expanding our understanding of celestial bodies and phenomena, particularly those that are obscured by dust clouds or too faint for optical telescopes to detect. Spitzer's innovative technology allowed astronomers to study the formation of stars, galaxies, and planetary systems, enhancing the representation of these celestial entities in scientific illustrations and research.
