Astronomy Fan and Desert Worlds

Why am I so fascinated with astronomy?  I know it's unlikely I ever will set foot outside of Earth.  And I know most planets and moons out there are hot and cold deserts.  Yet, I like deserts.  I live here on Lulu Island, which is a desert.  There are living, even habitable, worlds out there, exoplanetists know.  My imagination compensates for unsatiated reality.
