To celebrate NASA’s Spitzer Space Telescope’s 16th birthday, the Hubble Space Telescope team decided to put together a special present for their fellow “observing buddy.”

Hubble and Spitzer have observed many of the same astronomical objects over the years; and with Spitzer getting data from infrared, and Hubble getting data from visible, ultraviolet, and some near-infrared, the two telescopes have helped uncover some of the mysteries of the universe.
