Concept of a space telescope able to see the planets and even the satellites around the nearest stars

The Space Telescope will be launched in 1986 and will improve considerably our observational possibilities, but not the visibility of outer planetary systems.The solar system as seen from Alpha Centauri is presented, as well as the nearest stars and the main cameras of the Space Telescope.As a possible improvement the action of a distant and star-shaped screen is described; that screen is 100 to 800 meters and placed 10⁵ to 10⁶ km in front of the telescope; it allows one to avoid the dazzling effect of the stars and to look for planets such as Jupiter and Saturn up to 20 to 40 light-years. Such planets as Earth and Venus are a little less visible.The visibility of satellites such as the Moon is discussed; it remains at the limit of our technical possibilities.This conceptual paper does not consider in detail the technical difficulties involved.
