Text, MYTH versus REALITY 
 
Myth side 
 
Text, The same stars have been around forever. 
 
Reality side 
 
Text, Every star eventually dies. The matter from those stars is recycled back into their surroundings, even becoming part of new stars. New stars are constantly forming from clouds of dust and gas called molecular clouds. Stars have been forming throughout most of the universe's history. Some stars are very old, but others have formed quite recently.
