The Rosette Nebula in Orion, contains a core of recently formed hot blue stars which are actively hollowing out the gas and dust cloud in which they formed. A typical feature of such nebulae is the presence of ‘Dust Pillars’ or ‘Trunks’, knots of somewhat denser material which resist the stellar wind and intense UV radiation which has driven out the surrounding gas and dust. These features can clearly be seen here as complex dark structures to the lower right. This image is a narrow band composite of hydrogen-alpha and oxygen-III wavelengths of light, mapped to red and blue respectively.
