They reflect and scatter visible light that comes from an external source.
some celestial objects cant shine because some of them do not let light escape.But some actually shine because some of them allow light to escape.
Because they still absorb and scatter some light.

The total eclipse of the Sun by the Earth's Moon still leaves a corona of light, and the other visible stars shine just as brightly.
The light with the longest wavelength, which is still visible for us, is red light.
Black, an absence of visible color, appears such because it absorbs the visible light spectrum when struck. White is the presence of the entire visible light spectrum, and as such absorbs very little light. This is why white objects do not heat as quickly as black objects when left in direct sunlight. Of course, the heat that is actually stored by any object is infrared, which is why even with a pure white surface, that surface still captures some heat.
Objects which do not give out light can still reflect light.
Unless it`s colored glass, it will still shine its original color.
Mars has mass, and mass reflects radiant energy such as sunlight. Against the dark background of space, Mars reflects enough light to be clearly visible even across the solar system, at a distance of over 200 million miles. Of course, the Sun's light is quite intense, so that even a LITTLE bit of reflection makes it quite visible. Objects far smaller than Mars, and far more distant, are still visible.
The term "black light" is commonly used to refer to ultraviolet waves that are invisible to the human eye, but still carry energy. Some materials have the property that they can absorb UV energy and then re-emit it at visible wavelengths. The eye and brain interpret these visible waves as having colours.
It will "SHINE" for 10 years after it's extinction IF you are 10 light years away from it
Animals eyes shine in the dark because of the tapetum lucidum. This layer of tissue does not dissipate after death, so an animals eyes will still reflect the light after it died.
