Thank you - very interesting....and you solved a problem I have been stuck with for years. In my novel, a species evolved within a nebula. Then there was a tremendous explosion and they all died - they think. They have survived since then as souls and Robert named them the Sparklers.
My characters try to find a neula suitable for them, but no go, nothing matches with what they recall from millions of years ago. Perhaps they did not examine a Bok Globule?
If I use this info (and maybe a photo of yours?) I will acknowledge you.
