Many objects give off light; take the sun for example. The sun is basically a constant explosive chemical reaction on a grand scale. Actual elements (mostly helium and hydrogen) are being fused and split in a continuous, highly energetic cycle known as nuclear fusion; where hydrogen nuclei are fused together to create helium, which is then burned and converted back into hydrogen. Light is emitted every time this process occurs for each atom. The energy lost by the atoms takes the form of a quasi-wave particle or photon-quantum. This photon is essentially light. Together, many of these wave-particles (of varying wavelengths) will become visible light, while others will inhabit the non-visible portions of the electromagnetic spectrum. Planets and other objects in our solar system are visible to the naked eye only because they reflect the light of the sun into our eyes.
Luminescent. If is a biological process, it is called bioluminescence.
The sun is a natural object that emits light in the form of electromagnetic radiation, including visible light. Artificially, light bulbs and LED lights are examples of objects that produce light.
because there is no light for it to reflect off
The sun gives off light through a process called nuclear fusion in its core. This light then travels through space and reaches Earth, where some of it is reflected off surfaces like clouds, water, and sand.
The photosphere gives off heat and visible light.
A star

A torch emits light from the bulb. A mirror gives off light by reflection.

If an object gives off light, it is a luminous object.The luminous object gives off its energy and we see it. If you shine light on an object, it is an illuminated object, it just reflects the light back into your eyes.
A filament.
The amount of light a star gives off is the intensity or luminosity. Absolute Magnitude measures the amount of light given off.
When light hits a green object, the object absorbs all the colors in the light spectrum except for green. Green is reflected off the object, which is why we perceive it as green. This reflection is what gives the object its color.

light relflects off of the object you are looking at and your retna gives it color as your brain flips the object right-side up
The sun. All other objects reflect heat and light from the sun.
