Jupiter is not luminous in that it emits light, it reflects the Suns light so that it is visible to us on Earth. See also Albedo.
Halley's Comet is non-luminous itself; it does not emit light like a star. However, it becomes visible in the night sky as sunlight reflects off its surface, making it appear luminous to us on Earth.
A spectrograph tells us which colors (wavelengths of light) are in a luminous source.

Non-luminous. Objects which produce light of their own or give out or emit their own light are called luminous objects. Objects which do not produce light of their own, on the other hand, are called non-luminous objects. Luminous objects are objects like stars, sun and other celestial bodies which give out their own light. Objects surrounding us are not such light emitting objects. Therefore, we are surrounded by non-luminous objects.
