Stars, quasars, clusters, nebulae, galaxies, superclusters, the CMBR (Cosmic Microwave Background Radiation).
It must either reflect light, as in the case of the Moon under ordinary circumstances, or block light, as in the case of the Moon during a solar eclipse. Of course in everyd…ay life, almost everything we see on Earth is seen by reflected light. PS: in reality, every object with a temperature above absolute zero, in other words, every object, emits light in the form of infrared radiation. We just can't see it without instruments or special cameras.
The Sun. And also: when electrons go from excited state back to ground level, the energy that they had transforms into light which is given off.

Stars emit visible light.
Black holes do not, themselves, emit light. But the area around them does. Not light as we think of it, but highly energetic X-rays caused by the mass AROUND the black hole as… the matter spirals down into the black hole. As the matter falls in to the black hole, the gravity accelerates the mass to near lightspeed, and the matter - dust and gas, as nothing larger could survive the tidal forces - collides with other dust and gas particles and gives off X-rays. So while we cannot directly observe a black hole, we CAN observe the X-rays with no apparent source. The first black hole ever "discovered" was Cygnus X-1 - a strong X-ray source in the constellation Cygnus from which we couldn't see the star generating the X-rays.
Stars, except for artificial creation of light that we, or aliens may produce. (Light bulb, nuclear explosions, flashlight, etc.)
The sun emits it's own light because of its light
if you count it with heat it would be a star
black hole as they have a very powerful gravitational pull such that even light could not escape its gravity and fall into it
sun, stars, galaxies, nebulae, and meteors
planets, moon,etc do not emit light on their own.
Any sun-like star emits its own light. The Moon, and similar planets, simply reflect the light from the Sun.
Only stars can create their own light
