Odd I stumbled on to this site obviously from a google search how long does vic w/d last and felt compelled to read every post. I am sitting here at the 24 hour mark and its not dreadful but it is pretty bad.
The best estimate from a 1999 study set that number at about 125 billion galaxies, but a 2013 study - after the Hubble Space Telescope was upgraded considerably - indicated that there are 225 billion galaxies in the observable universe.
There is no universal naming convention for galaxies, as they are mostly catalogued before it is established whether the object is or isn't a galaxy. Mostly they are identified by their celestial coordinates together with the name of the observing project (HUDF, SDSS, 3C, CFHQS, NGC/IC, etc.).his is a general list of galaxies, for more specific lists, see lists of galaxies. Size (left) and distance (right) of a few well-known galaxies put to scale. This is an incomplete list that may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.
