SECTION #2: THE LIFE CYCLE OF STARS
Even though stars are not living things, we think of them as having a "life cycle." All stars form, or are "born," and when they run out of the hydrogen fuel needed to do nuclear fusion, they "die." Just what happens to a star throughout its life cycle depends on its mass. Low mass stars like the Sun live longer and die differently than larger, high mass stars which lives for a short period of time.

Small and average stars, like the Sun, will undergo a relatively peaceful and beautiful death that sees them pass through a planetary nebula phase to become a white dwarf, which eventually cools down over time and stops glowing to become a so-called "black dwarf".
Massive stars, on the other hand, will experience a most energetic and violent end, which will see their remains scattered about the cosmos in a enormous explosion, called a supernova. Once the dust clears, the only thing remaining will be a very dense star known as a neutron star, these can often be rapidly spinning and are known as pulsars. If the star which explodes is especially large, it can even form a black hole.
Who am I?
A huge cloud of gas and dust that begins to shrink under the pull of its own gravity. I am
the beginning of all stars’ lives.
Who am I?
Toward the end of life of an average star, it swells up into a giant star before losing its outer layers in an explosion that creates a planetary nebula.
Who am I?
These are small and hot and are the shrunken remains of an average size star. Their nuclear energy supplies have been used up and this is the last stage in the life cycle..
Who am I?
When gravity overcomes the nuclear energy in a red supergiant, the star begins to collapse, leading to
a massive explosion that can remain visible for months
Who am I?
If an object greater than four times the size of the Sun is left after a supernova. The gravitational pull is so great, not even light can escape.
