Generally true, planets don't emit their own light, but are visible largely because of reflected light, the illumination provided by their star, in the case of our solar system, by the Sun. Some planets might produce trivial amounts of light by other means, for example from lightning, volcanism, mineral fluorescence, etc.
Galaxies are made partly of stars, which produce light. So, in that sense, yes.
They produce their own light.
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
Well, thunder doesn't actually produce lightning. Lightning produces thunder.
