Hubble data was initially stored on the spacecraft in reel-to-reel tape recorders but these were replaced by solid state data storage facilities during serving missions 2 and 3A. Hubble transmits about 140 gigabits of raw science data every week.

The Corrective Optics Space Telescope Axial Replacement(COSTAR) system was designed to correct the spherical aberration for light focused at the FOC, FOS and GHRS. Spherical aberration is the condition when there is a loss in the definition of the image arising from the surface geometry of a spherical mirror or lens. Hence to solve this  condition COSTAR was designed.

Astronomical data taken with CCD (charged couple devices) must undergo several calibration steps before they are suitable for astronomical analysis.

The unique windows on the universe enabled by Hubble are Hubble deep field, Hubble Ultra-Deep Field and Extreme Deep Field.

All images from Hubble are monochromatic gray scale, in which its cameras incorporate a variety of filters each sensitive to specific wavelengths of light.

The GHRS was a spectrograph designed to operate in ultraviolet light. It was installed on the Hubble Space Telescope during its original constructing and it was launched into space as a part of the space telescope abroad the space shuttle on April 24,1990.

To fit the COSTAR system onto the telescope one of the other instruments had to be removed, and astronomer selected the High Speed Photometer (HSP) to be sacrificed.

The instruments of hubble that analyses light from the universe such as cameras, spectrographs and inter ferometers helps in observing the near UV (ultraviolet range) to IR (infrared range).
