Talk:Calabash Nebula

What does this mean?
"PPN) 1.4 light years (13 Pm) long and located some 5,000 light years (47 Em) from Earth in the constellation Puppis."

What are "13 Pm" and "47 Em" ? It looks like they should either be references or measurements, but I can't figure it out. --Keflavich 20:17, 12 May 2007 (UTC)


 * Petametres and Exametres. See SI prefix. Modest Genius talk 19:38, 13 April 2008 (UTC)


 * It's geekdom. To me they seem essentially useless values since readers who might know what they mean would most definitely be able to interpret "light year". From the perspective of producing an approachable public encyclopedia, it would be better to use scientific notation and list the values in metres or km; or else leave them out entirely. :-) &mdash;RJH (talk) 18:54, 6 November 2009 (UTC)

Reference to the game Halo
Should the reference to the game Halo be deleted? It gives no encyclopedic-material. --Rochelimit (talk) 22:03, 22 December 2010 (UTC)


 * Agreed. Besides, trivia sections are a no no. --213.249.213.41 (talk) 00:51, 29 June 2012 (UTC)

Magnitude is wrong
The magnitude of 9.47 is for the brightness in far infrared (J-band). The visual brighness in the V-band is much dimmer, probably <18. — Preceding unsigned comment added by ThomasK Vbg (talk • contribs) 11:57, 9 March 2021 (UTC)
