Stars produce energy from the fusion of hydrogen into helium during the main sequence stage of their life cycle. This is when a star is stable and balanced, and the fusion of hydrogen into helium in its core generates the energy that makes the star shine.
The two competing forces in a star are gravity, which tries to collapse the star under its own weight, and nuclear fusion, which generates energy and causes the star to expand outward. These forces balance each other to maintain a stable, long-lived star.
The Sun, like all stars, generates energy by fusion reactions deep within the star, where the heat and pressure cause atomic nuclei to fuse into heavier elements. Most of the Sun's energy comes from fusing hydrogen into helium.
This could be a star, such as our sun, which generates energy through nuclear fusion in its core. Stars are composed mostly of hydrogen and helium gases. When hydrogen atoms combine under immense pressure and heat, they release energy in the form of light and heat.
A star is born from a cloud of gas and dust in space when the material collapses due to gravity, causing it to heat up and ignite nuclear fusion in its core. This fusion process generates energy and light, allowing the star to shine and continue to evolve throughout its lifespan.
A star.
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
Hydrogen
A protostar generates energy by friction whereas a main sequence star generates energy by fusion.
A supernova explosion releases greatly more energy than our Sun in its entire lifetime.
Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.
Generator generates electrical energy. It uses mechanical energy and transforms it.
A large ball of gas that generates its own energy is called a star. Stars achieve this by undergoing nuclear fusion reactions in their cores, converting hydrogen into helium and releasing tremendous amounts of energy in the process.
A Horizontal Branch star generates energy through the fusion of helium into carbon and oxygen in its core. This fusion process releases energy in the form of light and heat, which provides the necessary support to balance the star against gravitational collapse.
No, the sun is not a planet. It is a star, specifically a medium-sized main sequence star that generates energy through nuclear fusion in its core. Planets orbit stars, including our sun.
It shines (it generates light).
