How does a star work
How do they form, live, and eventually die Learn more about these distant objects and their major importance in the universe. A star is a huge sphere of very hot, glowing gas Stars produce their own light and energy by a process called nuclear fusion
Fusion happens when lighter elements are forced to become heavier elements When this happens, a tremendous amount of energy is created causing the star to heat up and shine Stars come in a variety of sizes and colors. The simplest way to describe a star is that it is a great ball of fire, but it is more complicated than that
A star is a giant ball of hydrogen turning into helium through nuclear fusion.
These large, swelling stars are known as red giants But there are different ways a star’s life can end, and its fate depends on how massive the star is. The pleiades, an open cluster of stars in the constellation of taurus A star is a massive, luminous ball of plasma that is held together by its own gravity
The nearest star to earth is the sun, which is the source of most of the energy on earth Other stars are visible in the night sky, when they are not outshone by the sun. Life cycle of a star what is a star A star is a giant sphere of extremely hot, luminous gas (mostly hydrogen and helium) held together by gravity
