Ok this is a Cool Space Pic of the Day, tho not of this day but a prior day, a very prior day if you include how long it took to get here, which would make the trilobites look like mere glimmers in their Ancestral Units' beady little eyes. Neat pic of a cool galaxy, whatever caused it, PGI or an intergalactic fender bender.Click here: APOD: 2002 September 9 - Hoags Object: A Strange Ring Galaxy or maybe cut and paste http://antwrp.gsfc.nasa.gov/apod/ap020909.html
