Life Cycle of Stars

Front

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

Back

nebula

Front

The main force pulling a nebula together is: thermal expansion, singularities, gravity, microscopic adhesion

Back

gravity

Front

A star is born when: nuclear fusion starts, core contracts and outer gases expand, hydrogen is used up in fusion processes, planets form

Back

nuclear fusion starts

Front

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

Back

gravity and fusion

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

Front

When a massive star begins to cool and expand it is known as a:

Back

Red Supergiant

Front

When the core of a Red Supergiant collapses, a bright event occurs, known as:

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
