What color is nuclear fusion?
Stars shine due to nuclear fusion. The visible light produced by our star (the Sun) comprises all the colours of the spectrum as evidenced by a rainbow.
What causes a Stars brightness?
Stars shine because they are gigantic burning hot gas spheres that release heat and light. They are so bright because there are atomic reactions inside them, that convert hydrogen into helium. Their temperature can reach 10.000 degrees centigrade.
Do planets stars and comets shine as a result of reflected light?
Planets and comets shine because of reflected light because they do not produce their own light. Stars are enormous balls of gas that are undergoing fusion which releases a very large amount of energy in the electromagnetic spectrum which includes visible light. So stars shine because they produce their own light and not because they reflect light.
If nuclear fusion in the suns core suddenly stopped working today would the sky be dark in the daytime tomorrow?
It has been calculated that it would take roughly 8 years from the end of fusion in the core to the surface of the sun beginning to cool. It would then take 8 minutes before we would notice this cooling on the earth.
How can the sun's rays reach earth when earth is so far away?
The sun is extremely hot, a self sustaining fusion reaction. Between the earth and the sun there is nothing, it is a vacuum. There is therfore nothing to stop or absorb the rays until they hit earths atmosphere.
What is the critical temperature the core must reach for a star to shine by fusion?
about 10500-11000k is when fusion commences which creates the shining of the star
What type of nuclear energy allows stars to shine?
Fusion.
What is the difference a fission and fusion?
fission is the splitting of atoms of uranium or plutionium by the means of neutrons. fusion is the opposite. fusion is the violent combining of atoms through magnatism and heat. our own sun uses fusion to shine.
How many stars are there and why they shine?
Innumerable stars are there in the space. Our sun is also a star. Almost all stars shine because of fusion of hydrogen nuclei.
What energy source would allow the sun to shine 5 billion years?
Nuclear fusion.
What color is nuclear fusion?
Stars shine due to nuclear fusion. The visible light produced by our star (the Sun) comprises all the colours of the spectrum as evidenced by a rainbow.
How do stars age and die?
stars are born from interstellar gas clouds, shine by nuclear fusion and then die
How stars age and die?
stars are born from interstellar gas clouds, shine by nuclear fusion and then die
Are stars that shine with predominantly blue light the lowest in temperature?
No. They are the hottest. The coolest stars shine predominantly with red light.
What is fusion in the sun?
That refers to the conversion of hydrogen-1 to helium-4. This process frees a lot of energy, and is what makes the Sun shine.
Stars Shine Because Of A Process Called?
Nuclear fusion. In the most common case, hydrogen-1 is converted to helium-4.
Do stars shine because of reflected light?
No, Stars generate light and heat through nuclear fusion. The moon reflects light
