Difference between Astrophysics and Planetary Science?

[lightningmil]

What are the main differences between Astrophysics* and Planetary Science? What are their roles? And, which of the two is responsible for the first cloud map of a planet outside of our solar system?

*I mean just the Planet Formation and Evolution part.

Planetary science is properly a subset of astrophysics.
Neither and both are "responsible" for the cloud map of an exo-planet.
Who gets the credit depends on where it was first published... but, since the map is from direct observation, I'd say it was "astronomy".
