LS 5039 is LSS 5039 it's a Galactic microquasar [emphasis on the capital G] ostensibly Galaxy & Galactic = [in the] Milky Way, and galaxy & galactic = the rest of the galaxies. Of course, that's okay if yer speaking English... ...in German _all_ nouns start with a capital letter [if I remember rightly], and what about all the folk that don't use a roman letter alphabet, or a basic alphabet at all for that matter...? anway, end of pedant points... Cheers John
