I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.
Great Wikipedia has got greater.

NGC 634 is a spiral galaxy, lying at a distance of 217.1 megalight-years[3] away from the Milky Way in the northern constellation of Triangulum. This object was discovered in the nineteenth century by French astronomer Édouard Stephan.[7] It is inclined by an angle of 82.4° to the line of sight from the Earth, and thus is being viewed nearly edge on.[5]

Supernova SN 2006Q was reported 2.5″ east and 1.0″ north of the galactic core in NGC 634, January 24, 2006. This was most likely a type II supernova[5] and reached magnitude 18.74.[8] Another supernova explosion was reported near the galaxy on January 2, 2008. It was positioned 16.6 arcseconds west and 20.2 arcseconds north of the Galactic Center and was designated SN 2008A. This event reached a peak magnitude of 16.7 on January 3,[9] and was determined to be a type Iax supernova.[5]
