Emission nebulae. Optical image of part of NGC 6559, a large area of emission nebulae. A nebula consists of gas and dust. An emission nebula has been heated by nearby stars until the hydrogen gas in it glows red. Star formation can take place when a nebula collapses. Dark nebulae (ones that do not reflect or emit light) are seen silhouetted against the emission nebulae. These nebulae are in the constellation Sagittarius.
