👉 Selenography is a field of science that studies the properties and behavior of light. It involves the use of telescopes to observe and measure the movement of light through different materials, such as glass or metal. Selenography can be used to determine the distance between objects in space, detect optical phenomena, and even predict the motion of celestial bodies. The field has applications in fields like astronomy, physics, and engineering, and it is a valuable tool for scientists and engineers who need to understand how
