Cosmic History Big Bang Cosmology is a well accepted theory (12-16 billion years ago) Gravity drives the formation of our Milky Way galaxy (11-14 billion years ago) Gravity drives the formation of stars, and nuclear fusion in stars produces elements such as carbon, nitrogen, and oxygen Our solar system formed 4.6 billion years ago. Our Earth and the other planets in the solar system formed around our star: The Sun

Light Travel Time Light travels at 300,000 km/s Astronomical distances are measured in light-years:  km Stars in our sky are many light- years away Center of the Milky Way is 28,000 light-years away Galaxies are millions to billions of light-years away.
