Hi Everyone. I was just read the article posted here at space about the Orion Nebula ( http://www.space.com/spacewatch/orion-c ... 00203.html ) and a question popped up! lol. Ok here goes. We all seen many pictures of different nebulas, but from my perspectives is that, those pictures never seem to change. The pictures shown on different webs site all seem the same. i.e. Orion nebula pictures taken say 5 years ago look the same as the one shown here today. Now is it the same picture shown over and over again or are the sizes and distances so great that we can’t discern the changes?
