Stars are 'born' inside a nebula where gases form together into an ever-growing 'clump' known as a prostar - a baby star
-
The star ignites and begins it's billions of years of burning. This is the start of what is know as the "Main Sequence" of a stars life.
-
The longest and most common stage in the life of a star
-
This is the approximate point of our sun's life. Scientists believe it took about 5 billion years for our sun to reach this stage
-
As the star begins to run out of fuel, the surface expands to release heat into space. The star is much larger now, but much less stable.
-
As the stability of the star weakens, the matter inside eventually decays in a violent explosion, often destroying any nearby planets. This is the death of a star...
-
Depending on the type of star, the supernova results in the creation of either a "white dwarf" or a "blackhole". Both are very dense groups of heavy elements.
