This short paper discusses the findings mentioned in the above article and should be available to interested readers through a Google search. A highly recommended, short, simple explanation of these new HST-ACS observations of this remarkable starburst system. The HST images are icing on the cake! @ ruf & Ignoramus, the paper mentioned gives a detailed explanation of what technique(s) were employed in determining NGC 1569s' distance & probable membership in the IC 342 group.

I thought the same thing. I would like to know the magnitude of the error in distance. How much further away is the galaxy than we originally thought it was? Ignoramus Says:
