Originally the whole Pac-Man nebula would have been one large dark molecular cloud – the stars that formed early on at its centre having progressively hollowed out the centre of the nebula. The gas in and around this central region is ionized by the copious UV radiation emitted by the central open star cluster (IC 1490), causing it to glow and providing the light by which this narrowband image was taken
