Hubble Space Telescope

A detailed view of the Hubble Space Telescope, showcasing its cylindrical body and intricate mechanical components against a dark background.

A 2.4-metre reflecting telescope in low Earth orbit, operated jointly by NASA and the European Space Agency. Launched in 1990 with a flawed primary mirror, repaired by astronauts in 1993, and serviced four more times before the Space Shuttle's retirement in 2011. Hubble has produced the deep-field images that anchor modern cosmology and remains, three decades on, the most-cited scientific instrument ever built.
