\Hub"ble Space Tel"e*scope\, n.
A large astromical optical telescope placed into orbit around
the earth, from which, in the absence of absorption and
distortion by the earth's atmosphere, clear high-resolution
images of astronomical objects can be obtained in the
visible, infrared, and ultraviolet wavelengths. The telescope
was launched into orbit on April 24, 1990. Since then the
telescope has taken thousands of images, many of them unique,
recording never before seen astronomical phenomena. Service
missions were performed in 1993 and 1997, during which
astronauts upgraded or replaced equipment on the telescope.
