The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope , but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy .
The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14 ...
Their length is believed to be 19.5 meters, with a diameter of up to 3 meters (120 in). [ 5 ] [ 24 ] A NASA history of the Hubble, [ 25 ] in discussing the reasons for switching from a 3-meter main mirror to a 2.4-meter (94 in) design, states: "In addition, changing to a 2.4-meter mirror would lessen fabrication costs by using manufacturing ...
NGC 2261 was imaged as Palomar Observatory's Hale Telescope's first light by Edwin Hubble on January 26, 1949, [4] some 20 years after the Palomar Observatory project began in 1928. Hubble had studied the nebula previously at Yerkes and Mt. Wilson. [4] Hubble had taken photographic plates with the Yerkes 24-inch (60.96 cm) reflecting telescope ...
This video clip shows a visualization of the three-dimensional structure of the Pillars of Creation. Closer view of one pillar. Pillars of Creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle Nebula, in the Serpens constellation, some 6,500–7,000 light-years (2,000–2,100 pc; 61–66 Em) from Earth.

The telescope used by Berkowski was attached to 6 + 1 ⁄ 2-inch (17 cm) Königsberg heliometer and had an aperture of only 2.4 in (6.1 cm), and a focal length of 32 in (81 cm). Commencing immediately after the beginning of totality, Berkowski exposed a daguerreotype plate for 84 seconds in the focus of the telescope, and on developing an image ...
Mapping (Metric) Camera (7.6 cm focal length) with 127 mm film, on Apollo 15, 16, and 17 (see Sherman Fairchild#Lunar photography) [1] Stellar Camera (7.6 cm focal length) with 35 mm film, on Apollo 15, 16, and 17; Panoramic Camera (61 cm focal length) with 127 mm film, on Apollo 15, 16, and 17
NICMOS was installed on Hubble during its second servicing mission in 1997 along with the Space Telescope Imaging Spectrograph, replacing two earlier instruments.. NICMOS in turn has been largely superseded by the Wide Field Camera 3, which has a much larger field of view (135 by 127 arcsec, or 2.3 by 2.1 arcminutes), and reaches almost as far into the in
