Talk:I Zwicky 18

Not as young as first thought

 * Hubble Finds 'Dorian Gray' Galaxy: galaxy now believed to be 1-10 billion years old because of presence of older stars. &mdash; RJH (talk) 21:28, 16 October 2007 (UTC)

4300 light-years across ?
Multiplying 59M lt.yr. by a quarter of an arc-minute yields a width of 4.3K lt.yr. According to the numbers provided on the article page, the galaxy is about 4-5K lt.yr. across, consistent with "smaller than the Milky Way".66.235.38.214 (talk) 18:11, 9 November 2012 (UTC)

Galaxy-name
It'd be nice if the article (and astronomy articles generally) could say a bit about exactly what the name actually means, the naming conventions etc. What's that "I" doing there in front, for instance? --Arvedui (talk) 02:09, 4 June 2013 (UTC)
