The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;
it's a big mirror in the back.
The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
The door on the Hubble Space Telescope covers the aperture to protect the sensitive instruments and optics inside from potential damage when not in use. By keeping the aperture covered when not observing, the door helps to shield these components from hazards such as micrometeoroids and sunlight that could degrade its performance.
Yes, the Hubble Space Telescope was launched with a flawed primary mirror rather than a missing lens. The mirror had a manufacturing error that affected its shape, leading to blurred images initially. This was rectified through a repair mission in 1993, successfully improving the telescope's performance.
HST is a Cassegrain reflecting telescope using the Ritchey–Chrétien design, with an aperture of 7.9' (2.4m). It has observational ability in the Ultraviolet, Infrared, and Visible light spectrums.
Telescope, hence the hubble telescope!
It does not have a magnification properly speaking since it works as a camera, not a visual telescope. The aperture of the Cassegrain-Schmidt mirror is 2.4 m. The main camera has 16 MB.
No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.

A flaw in the lens
the hubble telescope is a refracting telescope and it is the biggest one because the refracting telescope can only have a certain range of size for the glass lens because it can only hang on the telescope and it is aproximently 5 meters big the lens. hope it helped
The main difference between Hubble Space Telescopes and other telescopes is the fact that the Hubble is placed in outer space where it can observe without the distortion of the Earth's atmosphere.
The size of a telescope almost invariably refers to the size of it's objective lens, or mirror. It translates to how much light the telescope can gather, not "how big it can magnify", which is very secondary.

what is the comparison between Hubble telescope and Galileo telescope
The Hubble Telescope was named after its designer Edwin Hubble.
