Explore the mesmerizing world of stars, their life cycle from nebulae to black holes, different types like red giants and white dwarfs.
A star is a giant ball of hot gas that can be compared to a huge engine – hydrogen is its primary fuel.
Atoms in the core of stars join together in a physical reaction known as nuclear fusion,.
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.
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.
Helium sinks to the star's core and raises the star's temperature—causing its outer shell of hot gases to expand.
These large, swelling stars are known as red giants.
A star's mass determines its temperature and luminosity, and how it will live and die.
The more massive a star is, the hotter it burns, the faster it uses up its fuel, and the shorter its life is.
