Sol

Solar and Heliospheric Observatory (SOHO) takes pictures of the sun. This picture of our new green sun was taken just this afternoon.

Wow, things would be tons different if that was the case, wouldn't it.

Actually, as per NASA, it's an Extreme Ultraviolet ImagingTelescope image.

(EIT) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. This green image specifically looks at 195 Angstroms and the bright spots correspond to about 1.5 million Kelvin. The hotter the temperature, the brighter it is.
