The nebula are regions where stars are forming in the LMC. In fact, the brightest and largest on the middle left, is the Tarantula Nebula, with the young forming star cluster 30 Doradus. 30 Dor is notable for being the biggest, baddest star forming region in the Milky Way or its satellites--it hosts a few hundred stars more massive than sixty times the mass of the sun in it's core, and hosts the candidates for the highest mass stars observed, above around 150 solar masses. If placed 100 times closer to be where the Orion Nebula is, its illumination would cast visible shadows, taking up a quarter of the night sky with a surface brightness on average that of Venus.
