The video explores how data from the Solar Dynamics Observatory (SDO) is used to create visual maps of the Sun's atmosphere, resembling Impressionist paintings. By analyzing data from different wavelengths, scientists can track the heating and cooling of plasma in the Sun's corona. This process involves comparing pixel brightness over time to determine temperature changes, revealing that most coronal plasma is cooling after being heated by nano flares. These findings help scientists understand why the Sun's corona is hotter than its surface.
