Answer: The simple answer is that deep inside the core of the Sun, enough protons can collide into each other with enough speed that they stick together to form a helium nucleus and generate a tremendous amount of energy at the same time. This process is called nuclear fusion.
The nearest star to Earth is the Sun. For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen into helium in its core, releasing energy that traverses the star's interior and then radiates into outer space
Feb 12, 2009 · So why do stars shine? Because they have huge fusion reactors in their cores releasing a tremendous amount of energy. We have written many articles about stars here on...
Sep 16, 2023 · Why do stars shine? Stars shine due to the emitting energy from their surface. The energy is produced in their cores via thermonuclear fusion of hydrogen to helium.
4 days ago · Star, any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. This article describes the properties and evolution of individual stars. Included in the discussion are the sizes, energetics, temperatures, masses, and chemical compositions of stars.
Feb 14, 2020 · You don’t have to be a scientist to know that stars shine. It’s what they’re known for. But how and why they shine was unknown for thousands of years, and only became clear in the 20th ...
More massive stars must burn fuel at a higher rate to generate the energy that keeps them from collapsing under their own weight. Some low-mass stars will shine for trillions of years – longer than the universe has currently existed – while some massive stars will live for only a few million years.
