Talk:Little Dumbbell Nebula

message: Is the redirect to this page from Butterfly Nebula correct?
Just wondering here. 'Cause I've also sometimes heard M2-9 referred colloquially to as "Butterfly Nebula" or "Wings of a Butterfly Nebula," as well as Twin Jet Nebula. So, I'm wondering if we need to disambiguate "Butterfly Nebula" to link to both "Wings of a Butterfly Nebula" and to "Little Dumbell Nebula?" Mgmirkin 20:13, 25 October 2006 (UTC)
replies: text: * Okay, here we go: Little Dumbbell Nebula (M76, NGC 650 and 651) seems to note that it is alterantely named Cork Nebula, Butterfly Nebula, and Barbell Nebula, in addition to Little Dumbell Nebula. Might want to add any of those not yet in the article nad/or the appropriate redirects on wiki. Mgmirkin 20:39, 25 October 2006 (UTC)
replies: text: * Looks like redirects have already been put in place. Have listed the alternate names in the 'also known as' (parens). Mgmirkin 01:10, 4 November 2006 (UTC)

text: * However, Butterfly Nebula (M 2-9) also lists usage of the name "Butterfly Nebula." So, there seems to be a slight conflict over the naming conventions here. Mgmirkin 20:46, 25 October 2006 (UTC)
replies: text: * It seems like in this context, "Butterfly Nebula" is used as a shorthand for "Wings of a Butterfly Nebula," I don't know whether the shortened name is usaed sufficiently to be notable. But the above link, among others sources, seems to use "Butterfly Nebula" pretty interchangeably with the longer "Wings of a Butterfly Nebula." So, I'm fairly certain that said usage is notable. So, I'm kind of thinking that a disambiguation page would be handy. Makes me wonder if any other nebulas have the moniker "Butterfly Nebula?" Mgmirkin 01:13, 4 November 2006 (UTC)
replies: text: * Okay, it seems notable from ADS abstracts to call M2-9 "Butterfly Nabula." ,  . So, I'm definitely thinking that a disambiguation page for "Butterfly Nebula" would be handy... Both seem to have equal claim to the name. Possibly M2-9 has more claim to Butterfly Nebula than NGC 650/651, since NGC 650/651 seems to have a number of other names that are more commonly used and more appropriate: Little Dumbbell Nebula, Barbell Nebula, Cork Nebula, etc. Still, since both have claim to it, a disambiguation page might be the best way to go, especially if any other nebulae are colloquially referred to as "Butterfly Nebula."

replies: text: * Since there's been little discussion, and I'm guessing not many are watching this particular namespace/article for discussion, I've Been Bold and done a little cleaning up of the namespace. See 'Discussion' on Planetary Nebula M2-9 for more detail. Specifically, Butterfly Nebula now redirects to Planetary Nebula M2-9 rather than to Little Dumbbell Nebula, as I'm fairly certain that when most people think of "Butterfly Nebula", they're thinking of the pretty image related to "Wings of a Butterfly Nebula" or M2-9. However, there are AT LEAST 3 nebulae that all have at some point been referred to popularly as "Butterfly Nebula", and for that reason I've created a Butterfly Nebula (disambiguation) page including links to Planetary Nebula M2-9, Little Dumbbell Nebula and NGC 6302, with an AKA list of other names each one is known by. Hopefully this is non-controversial and improves the namespace. There's also a { {Redirect | Butterfly Nebula} } tag on the Planetary Nebula M2-9 page so that it lists the redirect and a link to the disambiguation page so if people were looking for one of the other nebulas not as commonly [as Wings of a Butterfly Nebula] referred to as "Butterfly Nebula", they can still find them easily enough. If anyone thinks this restructuring is in error, let's talk it out here and/or on Planetary Nebula M2-9's discussion page. But I think the edits across the namespace are pretty non-controversial. I ran it by Mangojuicetalk prior to Being Bold, and afterward. He seemed to think it was pretty non-controversial and the reasoning was sound (I assume). So, hopefully the moves are legit and nobody will take issue with them. Mgmirkin 17:00, 4 November 2006 (UTC)

text: Of course, this is only one source, but I'm sure that other sources will roughly agree that multiple nebulas appropriate the name "Butterfly Nebula" to describe them (astronomers aren't the most imaginative bunch, are they?). So, the question becomes either disambiguation, or which nebula is most commonly conjured up when you say "Butterfly Nebula?" To my mind, it would actually be M2-9, which is one of the most pretty and often cited/printed Bipolar nebula examples (outside of maybe Eta Carinae or the Hourglass Nebula?).
