NGC6729 - NGC 6729 – The R Coronae Australis Nebula -
The beautiful blue glow comes from starlight scattered by cosmic dust. Blue light is scattered more efficiently than red light – somewhat like the scattering of sunlight that makes our own sky appear blue, only with cosmic dust instead of Earth's atmosphere.
