Talk:Orion Arm

message: I propose a rearrangement of the Orion Arm article because the way it is structured leads to misunderstandings. Like someone said earlier, they were looking for the exact location of our solar system in the Milky Way Galaxy and that led to the idea of the solar system's position inside one of the listed Messier objects, which is wrong.
There should be a statement, somewhere at the beginning of the article that the solar system is located inside the local bubble. 
Basically the Orion Arm consists of several of these bubbles and they are surrounded by molecular clouds. Known bubbles inside the Orion Arm: the local bubble, Loop I bubble, superbubble gsh 238+00+09, Loop III bubble also the Loop II and IV bubbles(although I couldn't find their exact locations). Molecular Clouds neighbouring the local bubble: Taurus, Chameleon, Southern Coalsack, Corona Australis, G192-67, Draco, MBM11-12-13, etc. I have a bigger list, will update soon.

thread_title: Orion Arm structure

message: How far is our Sun from the edges of the Galaxy?  I don't just mean the outermost edge at the rim, I also mean "south" and "north" toward the "flanks" of the galaxy?  I'm asking not entirely for information purposes, but just how far one of Star Trek's starships would have to travel directly from Earth to get to the edge of the galaxy (and encounter that mysterious energy barrier that the genre has included as a natural hazard).

thread_title:  How far to intergalactic space? 

message: What is the source for this: The Orion Arm is named for its proximity to the stars in the Orion constellation? AFAIK, this makes no sense, since most stars that we see in the Sky are located in the Orion Arm. Albmont (talk) 22:26, 12 June 2009 (UTC)
thread_title:  Name 

message: The Orion Arm is currently known as an Arm of the Milky Way in its own right. It possesses many of its own star-forming regions, fluffs and clusters and it also has its own gravitational dominance in itself; albiet not as prominent as the Sagittarius Arm or the "star-graveyard-like" Perseus arm. The Orion Arm actually wraps itself around the Milky Way's Galactic Core and is not just a few-thousand-light-years-long spur, such as the 3-Kiloparces Arm or the Scutum-Crux Arm. 
Perhaps it would be best to recreate its contents. Sources include DK Encyclopedias, Britannica and the Hubble Telescope information. 121.96.158.240 (talk) 05:35, 8 April 2010 (UTC)
thread_title:  The Orion Arm as a Minor Arm? 

message: Where did the artists get the data for the positions of the objects marked on the "shape of the Orion Spur" image? They aren't in the original, unmodified image. (It has no labels at all.)
Many of the positions that I've found don't even come close to those indicated. None of the marked objects are mentioned in the paper cited in the picture's label.

thread_title:  Sources for objects in Orion Spur map? 

message: Within the article itself it says  "It is also referred to by its full name, the Orion–Cygnus Arm".
Shouldn't the name of the article be its full name rather than one of alias names? I know a lot of articles go by commonly referred to names but thought I would raise the question anyway. Darrenaustralia (talk) 06:33, 19 May 2022 (UTC)

thread_title:  Article name - shouldn't its full name be used?
