It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.

Why and how are various celestial objects luminous and non luminous?
Luminous objects are those which can produce or give out light of their own, while non-luminous objects cannot produce or give out their own light. Some examples of luminous objects would be the sun, stars, fireflies, glowworms and some deep sea fish Some examples of non-luminous objects would be the planets Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune and also Moons.
Why it is possible to see non-luminous objects?
It's often possible to see non-luminous objects if you illuminate them with a source of light, such as a flashlight, a candle, or a drop of golden sunshine. No object absorbs all of the light that falls on it, so some light is always reflected from it, and some of that reflected light finds its way to your eye. Once any of the light falling on the object has reflected from it, it's very much as if the object were self-luminous.

extend the battery to avoid to turn on the flashlight by accident, or contaminate the tube once leak. So some flashlights need to lock or remove the battery to conserve.

Are satellites luminous or non-luminous?
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.
