These are generally clouds of hydrogen and a few other gasses plus some ‘dust’ in the form of silica and carbon. The ‘emission nebula’ can be seen due to the presence of nearby hot stars that cause the gas to glow - usually giving off what’s known as Hydrogen alpha emission which is characteristically a reddish/pink orange colour whereas where the nebula is mainly dust the nearby hot star has it’s blue light scattered in our direction off the dust grains causing a ‘reflection nebula’ as the light is reflected off the dust grains. Where there is dust amongst the emission nebula you can get some amazing contrasts and detail.
