“The oldest stars in the Milky Way are 13.4 billion years, give or take 800 million years. This is somewhat close to what the age of the Universe is (which hovers around 13.7 billion years).

“To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years.”
