NASA captured the Black Sea turning brilliant turquoise from space

NASA's PACE satellite captured stunning images of the Black Sea turning brilliant turquoise during its annual phytoplankton bloom, caused by coccolithophores. These tiny organisms have reflective shells that brighten the water so much it's visible from space. This natural spectacle wasn't just a satellite find; astronauts aboard the International Space Station also snapped pictures of the bloom's swirling currents as it spread through the Bosphorus. This event highlights the incredible natural phenomena observable from space and the importance of satellite monitoring in understanding Earth's changing ecosystems.
