A star is any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. Of the tens of billions of trillions of stars in the observable universe, only a very small percentage are visible to the naked eye.

A star’s gas provides its fuel, and its mass determines how rapidly it runs through its supply, with lower-mass stars burning longer, dimmer, and cooler than very massive stars.

A star is a luminous sphere of plasma held together by gravity. It generates energy through nuclear fusion in its core — a process in which lighter atomic nuclei (typically hydrogen) combine to form heavier nuclei (like helium), releasing immense amounts of energy in the process.

As a star approaches the end of its lifespan, it no longer has hydrogen to transform into helium in its core. Unable to complete the nuclear fusion process, the star begins to succumb to gravity, slowly collapsing.

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.
