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.
Jupiter: orange and white bands. The white bands are colored by ammonia clouds, while the orange comes from ammonium hydrosulfide clouds. None of the four gas giant planets (Jupiter, Saturn, Uranus, and Neptune) has a solid surface, so all we see are just clouds in their atmospheres. Saturn: pale gold. White ammonia haze covers the whole planet and partially obscures redder clouds below. Clouds in Saturn's winter hemisphere are pale blue. Scientists think that because the rings are blocking the Sun in the winter hemisphere, things are colder there and the ammonia clouds are lower down than normal.
