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.

The Hubble Space Telescope does not have a traditional lens with an aperture like in a regular camera. It uses a primary mirror to collect light from celestial objects. The diameter of the primary mirror is 2.4 meters (7.9 feet), which allows it to capture clear and detailed images of the universe.

What kind of telescope is the hubble telescope?

Hubble has provided scientists and astronomers with valuable data and images of the universe since its launch in 1990.


Why hubble telescope have a stepped appearance?

The Hubble Space Telescope has a segmented mirror made up of smaller hexagonal mirror segments that work together to form a single large mirror. This segmented design allows for a larger aperture size than a single-piece mirror of the same size and also allows for easier maintenance and replacement of individual segments if needed.


Who was the hubble telescope named after?

The Hubble Space Telescope was named after astronomer Edwin Hubble, who made significant contributions to the field of observational cosmology.
