The photographs were recorded by NASA's Solar Dynamics Observatory, a spacecraft launched in February 2010 to keep a constant watch on the Sun from geosynchronous orbit above the Earth.
"Heliophysics, the study of the Sun and its influence on the planets and the space surrounding them, has important implications for our day-to-day lives. Although the space between the Sun and Earth appears empty to human eyes, it is actually full of particles and energy from the constant flow of solar wind emitted by the Sun. That space is affected by a complex, ever-changing magnetic field that influences our entire solar system. Increased understanding of the Sun helps us better explain and predict its impact not only on Earth's climate but also on the near-Earth space environment and how it affects sensitive human technology, such as communications systems and satellite electronics. As humanity continues to explore space, a deeper knowledge of solar activity will also make it possible to identify and solve problems involved in communications, data collection, spacecraft and satellite design, and the effects space radiation has on the human body."
