The Sun

If our eyes could see extreme ultraviolet light, the sun might look like this to us. This is the last 48 hours of the sun's activity, recorded by NASA's Solar Dynamics Observatory. The movie is updated every 30 minutes. Solar activity is recorded at a wavelength that allows us to see magnetic field lines (made visible by particles spiraling along them) created by disturbances on the sun's surface. Also available are movies of the sun recorded at various other wavelengths of light.
