Astronomy for Beginners Expansion card adds to the knowledge base of the SkyScout Personal Planetarium. Topics include: Objects in the Sky, Astronomical Distances, Star Hopping and Astro Trivia.
Judging by the names, my guess would be:
Astrophysics: Study of the physics and structure of the sky and what it contains (planets, etc).
Astronomy: General study of the sky, planets, etc and general behaviour of it without going too deeply into the physical make-up of it.
