Stars (of which our sun is one) are the only sources of light in space. Planets, moons, asteroids, comets, etc. all simply reflect starlight.

What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
A red light source and a green light source shine on a white screen what color will the screen be?
If the screen is actually white, it will absorb all light and appear black to your eye. If the screen appears white in normal light, all light will be reflected resulting in the combination of green and red (brown/yellow).
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
How are light rays coming from a point source of light different then larger source?
From a point source, the light spreads out in all directions and adjacent light waves diverge from one another. From a larger source, it appears more like the light waves are moving parallel to each other, with little divergence. It's a relative thing. From the perspective of Earth, the Sun's rays are all parallel to each other because the Sun is huge and also because we are so far away from it. So the key differences are: 1. Small, point like source. 2. Being close to the source. Combinations of 1 and 2 above produce more divergent rays. Either of 1 and 2 below (or a combination of the two) will produce more parallel rays that don't diverge much. 1. Large light source 2. You're far away from the source.
What will happen if you shine a white light in front of a black oject?
Unless it's space, it will reflect some light. This is because there is no man made shade of black that absorbs 100% of all light shone on it. Some natural examples of true black is pure carbon and space.
What is the source of all light in outer space?
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
How does a space probe live?
it gains all its energy from the sun or some source of light to survive on and for landing on a planet it uses air bags stuffed in it
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
What is the difference between light source and an illuminant?
The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.
Photons travel outward from a light source in?
the photons travel outward from a light source in all directions.
Can light travel through space?
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
Can stars be dark?
the space has no boundaries so trillions of stars are in the space it gets not enough light that is why the space is dark
Is a television a light source?
Yes, as long as the TV is on and in working condition.
What is a region in space that exerts a gravitational pull on all the matter and light around it?
Every region of space exerts a pull on all the matter and light around it.
What is the source of heat and light for all the planets?
The sun
What is the source of the heat and light for all of the planet?
the sun.
What is the source of heat and light for all of the planets?
