ADC for Amateur Astronomers
Greenbelt, MD Specializes in archiving and distributing collections of data that have been published by professional astronomers. Most of these data sets are in the form of computer-readable tables of numbers, rather than images. Amateur astronomers can find these data collections useful in looking up the properties and locations of celestial objects. This can help amateurs plan for observing sessions, and help them to better understand what they've observed.

Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer is the largest infrared telescope ever launched into space.
