Hi! I'm John Armstrong and I'm a planetary scientist at Weber State University in Ogden, Utah.

In my job, I build models of planets in my computer to figure out how their environments form and evolve over time. Planets differ greatly from one another because of their internal make-up, type of atmosphere, distance from the Sun, and other factors. I try to understand how these factors shape the overall nature of the planet.
