The extraordinary video above was made by NASA using SDO still images. Additional processing was added to enhance the visible structures. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet. This wavelength shows plasma in the solar atmosphere, called the corona, that is around 600,000 Kelvin. The loops represent plasma held in place by magnetic fields. They are concentrated in “active regions” where the magnetic fields are the strongest. These active regions usually appear in visible light as sunspots. The events in the video represent 24 hours of activity on September 25, 2011. Video, Photography, and Text Credit: NASA/GSFC/SDO
