Re: APOD: Plasma Jets from Radio Galaxy Hercules A (2012 Dec
Gents, While I look at all the APODS without much real understanding, one thing that I was wondering about when looking at the Jets from galaxy Hercules A was, wouldn't these black holes reach a density so crushing that they would explode like a miniature big bang or before that, like a nebula? I kn...

galaxys
But, my point is that any star in our galaxy, it seems to me, would appear to be as big as any distant galaxy, more or less of course, when looking through an earth bound telescope; therefore the "stars" in the field around a close view of a distant galaxy would surely be galaxys that are ...

I am new to this site and could not find a forum for dumb questions. I am a professional phoographer and understand perspective and focal lengths of lenses but I am having trouble understanding most galactic photos and the star or galactic fields around them. Is the field around them always other ga...
