A supermoon occurs when the Moon is full at the same time it reaches its closest point to Earth (perigee). The Moon illusion is a fascinating phenomenon where the Moon appears larger when near the horizon compared to when it is higher in the sky. This visual perception is a trick of the brain, with no definitive scientific explanation despite centuries of observation. Friends and photographers alike can appreciate the illusion’s breathtaking views when observing the Moon framed by landscapes. Various methods can debunk the myth of a larger Moon, such as holding an outstretched finger or comparing photographs taken at different heights.
Interestingly, while the Moon’s size remains constant, it often appears more yellow or orange near the horizon due to longer atmospheric light pathways filtering out shorter blue wavelengths. Theories surrounding the Moon illusion involve our brain’s processing of size and distance, often relying on foreground objects for context. However, as astronauts in orbit also experience this illusion, the exact cause remains uncertain. Ultimately, enjoying the beauty of the Moon, regardless of its seemingly exaggerated size, adds to the spectacle of the night sky.
