A graphical timeline of the stelliferous era is a picture timeline that shows when the stars of our universe were born and when they will die. It starts billions of years ago, when stars first formed, and goes all the way up till the end of the universe, which scientists think will be in trillions of years. Every star has a life-cycle, and this timeline helps us to visualize when each star will form, live and then die. It also shows how different types of stars can form and age differently.
