Incandescent Sun

Solar Dynamics Observatory – SDO images in the 171 Angstrom wavelength of extreme ultraviolet, show plasma in the solar atmosphere, called the corona, that is around 600,000 Kelvin.   Credit SDO NASA

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun.



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.
