The sun keeps shining and throwing out masses of heat, and calculations show that the fusion of hydrogen to form helium would enable it, and other stars, to keep going for billions of years. Of course we can't get there to examine it closely, but I think the evidence is mainly based on not being able to account for it any other way. Try the question in 'Sun and Stars' category to see if an astronomer can give you a better answer.
What else can I help you with?
Is it possible to manufacture helium?
No, it is not possible to manufacture helium. Helium is a naturally occurring element that is produced through the process of nuclear fusion in stars.
What form of energy is does a star possess?
A star primarily possesses nuclear energy in the form of fusion reactions occurring in its core. This fusion process converts hydrogen into helium, releasing large amounts of energy in the form of radiation, heat, and light.
What is the massive ball of plasma that shines?
The Sun is a massive ball of plasma that shines due to nuclear fusion reactions occurring in its core, releasing energy in the form of light and heat.
Suns energy is most likely the result of the?
Sun's energy is primarily the result of nuclear fusion reactions occurring in its core. These reactions fuse hydrogen atoms together to form helium, releasing a large amount of energy in the process. This energy is what powers the Sun and provides light and heat to our solar system.
What is the source of energy for sun to radiate?
The Sun's energy comes from nuclear fusion reactions occurring in its core. This process involves the combining of hydrogen atoms to form helium, releasing vast amounts of energy in the form of light and heat.
How can temperature either help fusion to occur or prevent fusion from occurring?
How can temperature either help fusion to occur or prevent fusion from occurring?
What is the process occurring in stars to produce energy?
Nuclear fusion
Does a red giant start have fusion occurring in its core?
Yes, a red giant is a stage in the life cycle of a star where fusion reactions are occurring in its core. The core of a red giant star typically consists of helium undergoing fusion into heavier elements like carbon and oxygen.
What is triple-fertilization?
Double fertilization + syngamy occurring in angiosperms is called triple fusion.
What fusion is occurring in your sun right now?
The sun is currently a main sequence star.
What is events of occurring in the sun?
Nuclear fusion: mainly of hydrogen into helium. To a lesser extent there is fusion of helium into larger elements - all the way to iron.
The hottest part of the sun?
The very center of the core, where nuclear fusion is occurring; millions of degrees.
What are sources of bright light in the universe?
Primarily stars, more specifically stars where fusion is occurring.
What important fact about the sun can be estimated based on the rate of nuclear fusion occurring in the core?
The energy output of the sun can be estimated based on the rate of nuclear fusion occurring in its core. This energy output is crucial for sustaining life on Earth and understanding the sun's role in the solar system.
Compare the role of nuclear fusion in the formation of Earth's naturally occurring elements and in the creation of synthetic elements in the laboratory?
Creation of synthetic elements in the laboratory is not based on nuclear fusion.
Which type of radiation would you look for in a star to demonstrate that nuclear fusion was occurring inside?
You would look for high-energy electromagnetic radiation like gamma rays emitted from the star. This type of radiation is produced during nuclear fusion reactions when light atomic nuclei combine to form heavier nuclei and release energy. Detection of gamma rays can provide evidence that nuclear fusion is taking place in the core of a star.
How does Betelgeuse emit light?
Like all stars, Betelgeuse emits light because it is very hot. The heat for that light comes from nuclear fusion reactions occurring in the star. Unlike in most other stars, the fusion is occurring in a shell around the core rather than in the core itself.
