PSI Senior Scientist Elisabeth Adams, her children and their friends held their 18th annual gingerbread planet cookie decorating party, which resulted in this array of delicious artwork. In addition to a regular selection of planets and moons, the assemblage of tasty treats also featured many dwarf planets, exoplanets, asteroids, rocket ships, and a rainbow comet.
