What is the resolution of the Hubble space telescope? What would the resolution of the Hubble Space Telescope be if it were a digital camera? Gigapixels? Terapixels?

Hubble is not like a regular digital camera in that it doesn't take a single image in one shot.

The Hubble's CCD cameras can take monochrome images at a resolution of 0.05 arc seconds. It takes a number of small mega pixel images at different wavelengths. The images are then artificially coloured and superimposed to give a coloured image.

Each of the images are quite small. Multiple images are stitched together to form a much larger mosaic.

All of the impressive images for Hubble are in fact composites of many small images.

If the Hubble Space Telescope proved that Hubble's constant is actually half as large as it is currently believed to be, what would the implied age of the universe be in comparison to the current accepted value?

The dimension of Hubble constant, $[H_o]-LL^(-1)T^(-1)=T^(-1)$. The dimension of thr reciprocal $[1/H_o]=T$ As of now, different estimates of $H_o$ have a range around 70 km/s/mega parsec. The reciprocal, after unit...

Can the US government or CIA use Hubble telescope as a spy satellite to view high resolution images on earth?

First of all, intelligence agencies around the world already have very high resolution satellite for exactly that. Regardless, the Hubble was not built to be a satellite to collect visual...

How powerful is the Hubble Space Telescope? Would it be able to view a man walking on the moon?

In good weather from a height-of 600 kilometers it can see an object about 15 centimeter is size on earths surface, Moon is 375000 kilometers average.So it can not see...

Considering the Hubble Space telescope was launched in 1990, how many megapixel does hubble telescope have? How is it able to keep up with modern technology?

The Hubble telescope collects data in analog form. That is because it is a concave mirror which collects light wave and sends them in a focused form to its receivers....

If scientists were to point the Hubble Space Telescope in any direction for a deep field photo would they be able to capture the beginning of the universe?

Universe was not transparent in the early stages. The galaxies are moving so fast that the light from them have not reached Earth.

What are some advantages and disadvantages for using an ultraviolet telescope? Why is at better/easier or harder to use a UV telescope than another telescope like a radio telescope or an infrared telescope?

So we have to send them to earth orbit above our atmosphere which filters radiations.Certain objects emit only radiation in UV range.So to study them we have to use UV...

A space-based telescope can achieve a diffraction-limited angular resolution of 0.14 for red light (wavelength 650 nm). What would the resolution of the instrument be in the ultraviolet, at 150nm ?

I suppose here I am dealing with the Raileigh Criterion that tells us the minimum angular (in radians) separation between two object (emitting light of wavelength $lambda$) to strart to...
