’n Saamgestelde beeld van jong sterre in en om die molekulêre wolk Cepheus B.

Hieronder is ’n lys van stervormende gebiede in die Melkweg en Plaaslike Groep. Stervorming vind plaas in molekulêre wolke wat onstabiel raak weens swaartekraginvloede. Hierdie komplekse kan oop sterreswerms vol jong sterre bevat, asook streke van geïoniseerde gas wat H II-gebiede genoem word. Sterre vorm gewoonlik in groepe van baie lede, eerder as in afsondering.[1]
