A: Yes. This is how Hubble Space Telescope’s cameras work: Light hits a CCD chip, where it generates small electric charges. The charge is then read out and converted into an image file, before being sent to Earth.
The electric charge generated by light is extremely weak because it is so weak that you can only see Andromeda (the nearest galaxy) with your naked eye. To build up charge, light must be collected long enough to be readable. It is impossible to do more with a weak charge. You get much more electricity from the Sun, which is the closest star. Galaxies can generate electricity but not to transform the electric charge into images.
All modern telescopes function in this manner.
