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 Hubble Space Telescope has a primary mirror aperture of 2400 mm ... Dark-adapted pupil sizes range from 8–9 mm for young children, to a "normal" or standard ...
Extremely Large Telescope, Chile – 39.3 m (1,550 in). Construction began in 2018, first light planned in 2028. [23] Thirty Meter Telescope, Hawaii, USA – 30 m (1,200 in). Construction began in 2014 but halted in 2015; as of 2022 it has not resumed. [24] Giant Magellan Telescope, Chile – seven 8.4 m mirrors on a single mount. This provides ...
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, 2009.
According to Lew Allen, the initial key design elements were specified by Edwin H. Land.They included i) solid state focal plane array, ii) integrated circuits for complex data processing, iii) large, fast optics with a 2.54 m (100 in) diameter f/2 primary mirror, iv) gigabit/s data link, v) long on-orbit operational lifetime for the imaging satellites, and vi) communication satellites to ...
About 11.5 billion years ago, a distant star roughly 530 times larger than our sun died in a cataclysmic explosion that blew its outer layers of gas into the surrounding cosmos, a supernova ...
The Hubble Space Telescope (HST) primarily observes visible light and near-ultraviolet. It was launched in 1990 aboard the Space Shuttle Discovery during STS-31 , but its main mirror had been ground incorrectly, resulting in spherical aberration that compromised the telescope's capabilities.
