Life Cycle of Stars

Front

Stars are formed from big clouds of gas and dust is known as:

Back

nebulae

Front

The main force acting on a nebula is: thermal expansion, singularities, gravity, microscopic adhesion

Back

gravity

Front

A star is born when:

Back

nuclear fusion starts

Front

The two forces battling it out for the stability of a star are gravitational forces and:

Back

thermal forces (heat) through convection

Front

A star that has ignited and has used up all of the hydrogen is called:

Back

Red Giants

Front

When the core of a Red Giant collapses it becomes a:

Back

White Dwarf

Back

Red Supergiant

Back

supernova

Front

After a supernova, the core can collapse into a neutron star, or if massive enough it can become a:

Back

Black Hole

Front

When a Red Giant's outer atmosphere drifts away it is now known as:

Back

planetary nebula
