Northern And Southern Hemisphere Of The Unvierse

[nick1o2]

I was woundering if the terms "Northern Hemisphere" and "Southern Hemisphere" (of the universe) are used a lot in either an astronomy or astrophysics concepts? Because i have see both those terms being used to describe some ideas for the universe, and i was woundering if anyone could give me some usefully links for them? I'm just hoping to find out the basics for them; Structure, any events that have happened there, etc.

It is strictly a geocentric issue. The northern and southern hemisphere merely identify regions of the sky observationally accessible from geological locations on earth.
