End of Spitzer

NASA’s Spitzer Space Telescope mission officially ended on January 30, 2020. For over 16 years, Spitzer has shown what the universe looks like in infrared wavelengths. The human eye cannot see infrared light. Infrared light have longer wavelengths than visible light wavelengths. Infrared light can penetrate dense clouds that have blocked many regions of the universe from our view. Spitzer opened a completely new view to the hidden wonders of our universe. Spitzer has detected planets and signs of habitability beyond our solar system. Spitzer has returned images of regions where stars are born, seen light from distant galaxies, and discovered a huge previously-unseen ring around Saturn, just to name a few of its accomplishments.
