About ObservatoryDB

A database of 104 telescopes, observatories, and space research facilities from around the world and beyond.

It covers optical and infrared telescopes, radio dishes and arrays, space telescopes, neutrino and gravitational wave detectors, and historic observatories. Each page lists the location (or orbit), the year it began operating, its size (mirror, dish, or detector scale), the operating agency, and a short profile of what it studies and what it found.

Search by name, location, or operator, or browse from the home page. Facilities still under construction are marked as such in the year field.
