Since the average person isnât making less than $20,000 per year (which they would be if $3,150 were two monthsâ salary), itâs clear that grandmaâs rule no longer holds. Weâre not saying that you shouldnât buy an engagement ring, but we also donât think itâs wrong to play with conventions every once in a while.
The pinkish-red color of nebulae, such as M42 in Orion or the Lagoon Nebula in Sagittarius, is really a combination of four different bright spectral lines of hydrogen gas. A hydrogen atom has a single proton at its center and a single electron in its outer region.
It's a simple question of scattering. The reflection nebula gain reflectivity due to particles of Carbon (usually diamond dust), Iron and Nickel. Now the size of these particles is very small, and is more comparable to the wavelength of Blue light rather than Red. Hence the blue end of the spectrum is scattered better while the Red is absorbed better. So they appear more blue than red. The frequency distribution in the light of these nebulae is similar to that of the illuminating star(s), which provides significant evidence that it is not self-illuminated, and is reflecting light of that particular star.
