NGC 2029 (also known as ESO 56-EN156 or the Dragon's Head Nebula) is an
emission nebula
An emission nebula is a nebula formed of ionized gases that emit light of various wavelengths. The most common source of ionization is high-energy ultraviolet photons emitted from a nearby hot star. Among the several different types of emissio ...
