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...

Is it possible to capture UFO images by the Hubble Space telescope?
The Hubble telescope is not used in the same way we might use a telescope in our back yard to gaze at the moon and planets. The Hubble is a...

How do images from the Hubble Space Telescope supposedly support "scientific creationism?"
The electromagnetic-wave signals from a space body helps designate the body with parameters like distance, mass and other dimensions and age from the time it started sending signals....

As the moon visits are still controversial to some people, why does NASA not use the Hubble Space Telescope to show images of the landing sites?
This has to do more with the human nature, as it is hard for someone to change their beliefs on something quickly - whether it's the moon landing/moon visits to...

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....

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...

Are the images taken by the Hubble Space Telescope just a compilation of waves, such as gamma, x-ray, UV, etc?
Only visible light, some infra red a nd some UV ranges.

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...
