<p>NASA's Aqua satellite, part of its Earth Observing System (EOS), on May 10 captured a strikingly&nbsp;colourful picture of the Celtic Sea, an area of the North Atlantic Ocean known for its maritime-rich ecosystems.&nbsp;</p>

<p>The image showed large colourful patterns on the sea of vibrant greens and blues stretched across. The colours could be attributed to phytoplankton bloom -&nbsp;microscopic plant-like organisms spread across the Celtic Sea.</p>

<p>The picture is illuminating for hundreds of kilometres and is simply breathtaking.&nbsp;</p>

<p>Aqua satellite carries several instruments onboard that observe various aspects of Earth's systems, such as the atmosphere, oceans, land surfaces, and ice. It provides valuable data for understanding climate change, weather patterns, and the Earth's water resources.</p>

<p>This dazzling display was due to phytoplankton bloom, a natural spectacle fueled by warming temperatures and increased sunlight. Satellites observed the colourful phenomenon for over a week with the MODIS instrument.</p>

<p>They are a primary food source for a wide range of marine organisms, including small fish, shellfish, and whales. They form the base of the marine food chain. It supports the entire ecosystem.</p>
