History of Astronomy Part 1: The Celestial Sphere and Early Observations

Now that we’ve learned about how the universe began, as well as the development of the Milky Way galaxy, the solar system, and the Earth, it’s time to learn about the human beings that came to inhabit the Earth. Eventually, they began to look at the sky and wonder about what they were seeing, which initiated a journey of discovery that has brought us to the knowledge we have today, and have been discussing throughout this playlist! How did our ancestors figure out all this stuff? Let’s go through the major breakthroughs over the next few tutorials!
