NASA | IRIS: The Science of NASA's Newest Solar Explorer

The video explores the journey of the sun's energy from its core to the outer layers, focusing on the chromosphere where temperatures rise unexpectedly. The IRIS mission aims to study this region in detail using advanced imaging techniques. The interaction of light and matter in the chromosphere is complex, requiring sophisticated modeling. Despite the corona's extreme heat, it requires minimal energy due to its low density. The video highlights the importance of understanding these processes to comprehend solar phenomena and their impact on the solar system.
