The Hubble's main mirror is almost 8 ft (7ft 10in) wide and has an area of 48 square ft.

The Hubble Space Telescope uses mirrors to gather and focus incoming light. The primary mirror is 2.4 meters in diameter and collects light from celestial objects to produce high-resolution images. Mirrors are well-suited for space telescopes as they are more durable and easier to shape to precise specifications compared to lenses.
Telescopes like the Hubble
I'm not aware of any telescopes that begin with the letter "Hub." Telescopes often have names like Hubble, which is named after astronomer Edwin Hubble, or Hubbell, which may be a variation or misspelling of the Hubble Space Telescope.
Because light is absorbed and disturbed as it passes through air ... effects that ground-based telescopes have to live with but Hubble doesn't.
The Hubble Space Telescope is not affected by atmospheric distortion, providing clearer images than ground-based telescopes. Ground-based telescopes have the advantage of being easier to upgrade and maintain than a space-based telescope like the Hubble.
All major astronomical telescopes are equipped with spectrographs, including the Hubble and Spitzer Space Telescopes.
The Hubble Space Telescope was launched from the space shuttle Discovery on April 24, 1990. The mission was designated STS-31.
The Hubble spacecraft has found more anbout the stars and planets more clearly then the others saw from other telescopes.
Telescopes like Hubble produce more detailed images than Earth-based telescopes because they are positioned above Earth's atmosphere, which can distort and blur images. This allows Hubble to capture sharper and clearer images of celestial objects. Additionally, Hubble's location in space enables it to observe wavelengths of light that are absorbed by Earth's atmosphere.
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
