Yes. Matter falling into a black hole heats up can can produce tremendous amounts of light. Nebulae can also emit light from interactions with high-energy particles. Some minor light sources have been obseved in this very solar system, and even on Earth. Earth, Jupiter, and Saturn all produce glowing phenomena called aurorae and, along with Venus, also have lightning in their atmospheres. Earth is frequently home to fires that burn organix material, emitting light. Lava flows on the surface also emit light. In other solar systems, some planets, especially newly formed ones, are likely so hot that they glow.
A primary light source is one that actually produces light, such as a light bulb or the sun. A secondary light source in one that ONLY reflects the light produced by a primary light source. It doesn't produce light itself, such as a mirror or the moon.
There is no 'primary light source', as in one object that provides most of the light. In this solar system, our sun provides the primary light source. Other stars provide most of the light for other areas of the galaxy. The source of the shininess is light reflecting off the atmospheres or gases surrounding the planet. Please note that you should restrict your posts to one question per post.
A visible object that is not a light source is any other object in the universe. Objects that are not light sources reflect light and are thus made to be visible.Examples include:planetspeoplethe mooncarsdogsflowersbooksrocks, either in daylight, or else illuminated by a flashlighta light bulb or LED with the power switched off
Light can be obtained from various sources. One common source is the Sun, which produces natural light. Artificial light can be obtained from light bulbs, lamps, LED lights, or any other device that emits light.
Definitely. Nuclear fusion is the source of all the light, heat, and other energy generated and radiated by every star you see, including the sun.
Everything in the universe, which has mass, is the source of gravity. Mass is the fundamental property of every object in this universe and it is due to this property that every object attracts other objects. So, earth is also a source of gravity.
The primary light source is the sun for the planet Earth.
Sun, Moon for light, Light bulb etc
School of Light. There really is no light designing school. There is schools for disorentating light and making other objects that emit light. I am sure that there might be in 50 years a school to create a natural light source out of nothing wiht out using all the regular light elements.
Pure white light then it starts over on the other side of the universe.
The other stars in the sky.
