Atlas of the Moon (Mädler)

The Atlas of the Moon, created by Johann Heinrich Mädler in the 1830s, is a detailed map of the Moon's surface. Using telescopic observations, Mädler and his colleague Wilhelm Beer charted lunar features such as craters, mountains, and maria (large flat plains). This atlas was one of the first comprehensive and accurate lunar maps, helping scientists study the Moon's geography and geology. It served as a foundational reference for future lunar exploration, illustrating the Moon's diverse landscape with clarity and precision, and marking a significant advancement in lunar cartography.
