Starship Asterisk*

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...

it occurs to me that Hercules, and other star clusters are ball shaped and therefore the center would always appear to contain a heavier concentration of stars than the outer edges. can the density of stars always be "counted" well enough to varify that the center is indeed more heavily co...

thanks Scott, that answered my question. I didn't realize that the galaxies would appear to be that much bigger than a star in our galaxy at those massive distances. That has bugged me quite a while.

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...
