Engineers did not have exoplanet science in mind when they designed the Spitzer Space Telescope in the 1990s, but thanks solid engineering, Spitzer’s observational powers were used far beyond original expectations.
10 Things Spitzer Taught Us About Exoplanets
An emerging idea, bolstered by three decades of science, is that there are "Goldilocks stars" — not too hot, not too cool, and above all, not too violent to host life-friendly planets.
Goldilocks Stars Are Best Places to Look for Life
One of NASA's four Great Observatories, Spitzer launched on Aug. 25, 2003, and has studied the cosmos in infrared light. Its breathtaking images have revealed the beauty of the infrared universe.
