I am getting to visit you more often these days ... and have to concentrate when I'm reading about this wondrous subject but I've said that before.
You did make me smile though at this comment from the Ghouls bit ...
"It contains a small cluster of newborn stars, and they are big babies. Each one is between ten and twenty times the mass of the Sun."
Only an astronomer could say something like that in such a matter of fact way, you know, like "I had some cake for tea yesterday."
Ag ja, thanks again.
