A final farewell to NASA's Spitzer Space Telescope
... and planet formation, the evolution of galaxies from the ancient universe to today, and the composition of interstellar dust. It also proved to be a powerful tool for detecting exoplanets and characterising their atmospheres. Spitzer's best-known...
