I am attempting to put together a small display to go in a case at the counter where my museum sells planetariums tickets. With all of the recent things going on with comets, I thought they would make a good topic. Unfortunately, there is no staff person in this department at the moment, so i'm stuck working by myself with no resources and no clue. What I'm looking for (at the moment) is a 3D model of a comet as well as a small poster/diagram explaining what a comet is. Can anyone tell me where I could find such things? None of the catalogs I have available show anything this general. Thanks in advance, and please reply off list as I dont see comets as much of a hot topic around here :) Vanda Bushfield Grad Student Texas Tech University
