    Suns are not Irish: The laws of radiative physics conspire in such a way that there are no Green stars in the Universe.

        @neiltyson couldn't the Doppler effect of a star moving towards you achieve a greenish/blue color shift?

        @TheBurrMan thanks - of course, his tweet afterwards then referenced OIII. Not sure I can take any credit though. ;-)

        @neiltyson Hmm, I always thought this was more a function of the biology of vision, than anything specific to hows stars radiate light.

        @neiltyson But... this is not true. There are stars which peak in the green range, our visual cortices simply combine signals and see white.
