If you go to: http://www.eso.org/outreach/press-rel/p ... 50-06.html the ESO has released a 256 million pixels image of the Tarantula nebula. That is really, really big: the download is at 211 MB.
... What gets to me isn??t exactly the nebula itself, but the number of stars visible around, and in front of it... It??s big.
