Sandy Island is a small, uninhabited landmass located in the South Pacific Ocean, near the coast of New Caledonia. It was first reported in the 19th century and appeared on various maps for many years. However, it was later discovered that the island does not actually exist, leading to confusion among cartographers and explorers. The island gained attention in 2012 when researchers conducted a study that confirmed its non-existence. This incident highlighted the importance of accurate mapping and the potential for errors in geographic data. Sandy Island serves as a reminder of the evolving nature of our understanding of the world's geography.
