The Hertzsprung-Russel diagram shows the life cycle of all stars.
The size of the star
between giant and supergiant stages of life
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
cause its life cycle appearence
Ultimately the mass a star has at the end of its life depends on its initial mass. This mass determines what stages a star will go through in its death throws.
protostar
The size of the star
between giant and supergiant stages of life
Usually it's from nuclear fusion. At some stages in a star's life it can get a lot of energy from gravitational collapse.
cause its life cycle appearence
It is approx half-way through its 10 billion year life cycle.
Giants and super giants are considered stages in the life cycle of a star.
How does the life cycle of humans compare to the life cycle of a star? They both have stages where they are born and die which is in the main sequence and supernova and in a human they are born in a womb and die of old age.
neutron star
first its a protostar then it move to a blue star, next the blue star changes to a red giant thehn a red supergiant then either a supernova or blackhole
The two opposing forces are gravity, pulling the star in and the outward force from the ongoing nuclear fusion reactions. As the star approaches the end of it's life, changes in the reactions occur, which cause the forces to balance out in different ways, changing the size of the star.
The Stages of Life was created in 1835.
