Understanding star requires examining multiple perspectives and considerations. Its total mass mainly determines its evolution and eventual fate. A star shines for most of its active life due to the thermonuclear fusion of hydrogen into helium in its core. This process releases energy that traverses the star's interior and radiates into outer space. Star | Definition, Light, Names, & Facts | Britannica. 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. Similarly, stars - NASA Science. 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.
| Scientific American. In this context, after all, we also know the sun is a star—but, by definition, we never see it in Earth’s night sky, and it’s certainly not a dot (unless you’re viewing it from well past Pluto, that is). Stars—facts and information | National Geographic. Helium sinks to the star's core and raises the star's temperature—causing its outer shell of hot gases to expand. In this context, these large, swelling stars are known as red giants.
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. Star - New World Encyclopedia. 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. Moreover, star – Definition & Detailed Explanation - Sentinel Mission.
From another angle, yellow Dwarf Stars: Our sun is a yellow dwarf star, with a temperature of about 5,500 degrees Celsius. These stars are medium-sized and are in the middle of the temperature range. 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. Another key aspect involves, stars come in a variety of sizes and colors. (article) | Stars | Khan Academy.
A star’s mass determines its temperature and luminosity, and how it will live and die.
