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.
Nebulae are often star-forming regions, such as in the Pillars of Creation in the Eagle Nebula. In these regions the formations of gas, dust, and other materials clump together to form larger masses, which attract further matter, and eventually will become massive enough to form stars.mission nebulae, such as the Eagle Nebula, are vast, glowing clouds of ionised hydrogen and dust where stars are born. Others, such as planetary nebulae, are the bright shells of gas shed by dying stars. Despite their name, planetary nebulae have nothing to do with planets.
