A mere 500 million light-years away

These are galaxies of the Hercules Cluster (http://www.astr.ua.edu/gifimages/hercules.html), an archipelago of island universes (http://antwrp.gsfc.nasa.gov/apod/ap051222.html) a mere 500 million light-years away (http://www.faqs.org/faqs/astronomy/faq/part8/section-14.html).

I wish Hercules was a bit higher in the sky! Still, will try to track this gxy cluster down next time I am under dark skies.
