Refracting telescope focus, results in a non-inverted and upright image. Galileo’s best telescope magnified objects about 30 times. Because of flaws in its design, such as the shape of the lens and the narrow field of view, the images were blurry and distorted. Despite these flaws, the telescope was still good enough for Galileo to explore the sky. The Galilean telescope could view the phases of Venus, and was able to see craters on the Moon and four moons orbiting Jupiter. Parallel rays of light from a distant object (y) would be brought to a focus in the focal plane of the
Face on Moon South Pole ultimately determines whether or not an image resembles a face. The craters of the moon that make up the ‘face’ on the south pole have been preserved for billions of years. The moon’s exterior is 16% composed of these craters. These craters have been made by meteors and can be up to 1,600 miles across. Due to the absence of an atmosphere, the moon cannot protect itself from outer threats like these meteors. Craters are often covered with a mixture of fine dust and rocky debris called regolith. Some research conducted through Clementine suggests that there is also water and
