Light, the electromagnetic radiation that we see, is emitted by an atom.
When an electron is moved into a higher orbit than its natural one, and then returns to the proper orbit, it emits light of a frequency unique to that atom.
So, by inspecting the light from a star, we may determine that it has calcium in it for example.
This is the same process by which neon tubes emit light, in that case reddish. Or Sodium street lamps give out an orange light.
Other parts of the electromagnetic spectrum are also emitted by these processes, but as we don't see them, we realize it. Radio waves, and x-rays are also given out by these processes, and indeed by the stars.
What else can I help you with?
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
Why the sun a star but the moon is not?
A star is an object that radiates its own heat and light. A typical star is a superheated ball of hydrogen and helium that releases energy through nuclear fusion. The moon is much smaller and less massive than any star and is mostly made of rock. It does not produce its own light, but simply reflects light from the sun.
Is a star a hot planet?
No, it is not. Stars are kept at very high temperatures by nuclear fusion, which only happens to bodies of high masses. The planet Jupiter is a body that was close to becoming a star, but was too small and did not.
What objects can be seen from earth because they produce their own light?
Cities can be seen from space.
Is a star a source of light energy?
Yes, a star is a source of light energy. Stars produce light and heat through nuclear fusion reactions that occur in their cores. This light energy is emitted in the form of electromagnetic radiation, including visible light.
What causes the light that the sun produce?
the sun is a star
What star produce its own light?
All stars do ... sort of by definition.
Is Mars a Main sequence Star?
No . Mars is a planet, not a star. "Stars" produce light, planets reflect light. Whether that's in our "Solar System" or any "Star system".
Why does a star produce light?
Because of nuclear fusion! The nuclear fusion releases energy which produces light.
What is a large object that circles a star but does not produce any of its own light?
moon
Why does moon don't gives light like sun?
Because the moon is not a star and only stars can produce light by itself.
What property did you use to classify a celestial body as a star?
Stars shine...they produce light. ght
How does a star work to produce light and energy?
Stars produce light and energy through a process called nuclear fusion. In the core of a star, hydrogen atoms combine to form helium, releasing a large amount of energy in the form of light and heat. This energy is what makes stars shine brightly in the sky.
Why doesn't the moon not make light?
The moon is not a star. The moon only reflects the suns light. Only stars make light. Our sun is a star.
Why the sun a star but the moon is not?
A star is an object that radiates its own heat and light. A typical star is a superheated ball of hydrogen and helium that releases energy through nuclear fusion. The moon is much smaller and less massive than any star and is mostly made of rock. It does not produce its own light, but simply reflects light from the sun.
Is Venus a star?
No, Venus is not a star. It is a planet in our solar system, the second closest planet to the Sun. Stars are massive celestial bodies that produce their own light through nuclear fusion, while planets do not produce their own light and instead reflect light from the Sun.
Is a star a hot planet?
No, it is not. Stars are kept at very high temperatures by nuclear fusion, which only happens to bodies of high masses. The planet Jupiter is a body that was close to becoming a star, but was too small and did not.
