👉 In the field of astronomy, photoheliography is a technique used to study and observe celestial objects using light. It involves taking images of stars, planets, and other celestial bodies in space, and then analyzing these images to determine their characteristics such as brightness, color, shape, size, and movement. Photoheliography has been used for centuries to help astronomers understand the formation and evolution of galaxies, as well as the properties of celestial objects like planets and moons.
