Interstellar Molecules
I believe that it is the linear C3 isomer that is known in comets and interstellar space. The Wiki list of molecules in interstellar space also appears to have it wrong. A reference would be helpful.

Concur. Embarrassingly (as the creator of the article) I just ran with the name listed in the aforementioned article without chasing up whether the structure had been elucidated as cyclic. Anecdotal ab initio simulation of the species (by myself, and I realise that wikipedia is not the place for original research, but this is to demonstrate ambiguity) suggests an approximately linear diene, so I'm rewriting the article and amending the descriptor in the interstellar space article to reflect the lack of info. I can't find any info on the standalone molecule 'C3' in interstellar space, only linear C3Hx species as described by Kaiser et al. 1997. It is however interesting to note that Kaiser et al. 1996 confirm linear and cyclic C3H species in interstellar space w/ ab initio confirmation of their stability.

Reading around some more has confirmed linearity of C3, a better article was also discovered at Tricarbon and this article was merged. Snarfevs 11:56, 30 October 2006 (UTC)
