In the near-vacuum of space, bare metal surfaces on the International Space Station can reach temperatures above 260°C. Why?
A. The side of the station facing the sun receives thermal energy via electromagnetic radiation.
B. As the station travels through space, a few atoms per second impact the surfaces and transfer their energy to them via conduction.
C. The heat is transferred to the surfaces by convection as the station moves through the thin fluid of space.
D. The side of the station facing deep space absorbs thermal energy radiated from all the stars on that side.
