It is one of the brightest nebulae, and is visible to the naked eye in the night sky.
The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies.
For observing smaller star clusters, nebulae, and galaxies binocular magnification is an important factor for visibility because these objects appear tiny at typical binocular magnifications.
Amino acids are basic constituents of life, and recent laboratory experiments demonstrate they can be synthesized in the gaseous nebulae that are the birthplaces of stars.
The results suggest that protoplanetary nebulae and asteroids\meteorites may be conducive to the origins of life, to early evolution, and to seeding the galaxy by natural or directed panspermia.
We have also addressed our discussion to the possible formation of petroleum fractions or petroleum-like organic matter, which could exist both in the interstellar medium and in the protoplanetary nebulae.
Since photographing stars or nebulae requires a long exposition time, it is therefore most susceptible to being affected by the wind and should be reserved for calm nights.
Nucleosynthesis in stars determines the elemental and isotopic composition of protostellar nebulae, which probably develop with systematic relationships between nominally reducing and oxidizing components and between stable and radioactive nuclides.
