Sea of Stars Maldives: A natural phenomenon known as the Sea of Stars occurs in a few coastal locations worldwide, including the Maldives. The phenomenon is caused by bioluminescent phytoplankton, which glows blue-green when disturbed by movement like waves or a passing boat. When the right circumstances are met, these planktons produce an amazing show that mimics a starry night sky. The light particles illuminate the waves, giving the scene an ethereal, dreamlike appearance.
