I'm trying to make the edge of an earth model glow like it would viewing it from space. Any ideas?

Simple way would be add a glow from under the special effects tab in your earth shader.

or add a sphere with volume shader for the Ozone layer, and add a glow to this 2.

create a sampler-info node and input its facing ratio attribute into the v-cord of a ramp texture. Then use the ramp texture to make the atmospheric glow more apparent on the edges. Here is a tutorial on how to make a ghost shader that explains this setup:
