Scientific paper

The head of Cometary Globule 1, a dense dust cloud with a faint luminous tail, is illuminated by a variable F2 IIIe star. The age and distance of this star, and hence of the globule, are discussed. It is proposed that the form of the globule is described well by Woodward's model of a spherical cloud through which an initially plane shock has passed. This seems to be the only means to eject dense material downstream as has happened in the tail of Cometary Globule 1. If the illuminating star was formed by the implosion of the cloud and has since drifted to the front edge, comparison with the models suggests that the implosion occurred 1.2 ± 0.6 million years ago.
