<s>[INST] Similar to the Elephant Trunk Nebula, the Pelican Nebula is also thought to have been formed by the radiation pressure from massive, hot stars. As with the Elephant Trunk Nebula, some of the cooler gas in the PelicanNebula has condensed into clumps of denser material, forming dense interstellar clouds. These clumps of denser material can be the nuclei of a new stars in the future. In the space between the dense gas and the diffuse emission, an ionization front can be seen with a gaseous interface between the denser material and the diffuse material, created by the ionization of the denser material by the strong radiation pressure from the nearby massive, hot stars.[/INST]
