* The Universe: The universe is estimated to be around 13.8 billion years old.
* First Stars: The first stars formed shortly after the Big Bang, perhaps a few hundred million years later. These early stars were massive and short-lived, but they were the first to shine in the universe.
* Our Sun: Our Sun, a relatively average star, formed about 4.6 billion years ago.
So, while the stars have been shining for nearly the age of the universe, the particular stars we see in the night sky have been around for different lengths of time, depending on their size and age.
Remember, stars are constantly being born and dying throughout the universe, so the night sky is ever-changing!
