On August 12, a total solar eclipse darkened skies over Greenland, Iceland, and Spain. During this phenomenon, the Moon completely covered the Sun, briefly revealing the Sun’s wispy outer atmosphere, known as the corona, to observers located in the path of totality who were fortunate enough to have clear skies. NASA researchers and photographers deployed along the eclipse path to document the event from various perspectives.

Observing the solar corona during a total eclipse is crucial for understanding its structure and dynamics, as it is normally obscured by the intense brightness of the solar photosphere. These events offer a unique opportunity to study phenomena such as coronal mass ejections and the solar wind at their origin. The data collected by NASA, including images and measurements from ground, air, and space, will contribute to improving models of the solar atmosphere and its impact on space weather.

The observation campaign included ground-based teams at strategic points, flights of specially instrumented aircraft to extend the duration of totality observation, and the use of orbiting satellites. This multidisciplinary approach allows for a comprehensive view of the event, capturing details at different scales and across various wavelengths. Preliminary results from these observations are expected in the coming months, following a thorough analysis of the data.
