From the original series with Carl Sagan, I learned from episode 1:
1) The same laws of physics apply throughout the Cosmos. The same elements exist as well.
2) The Milky Way Galaxy is estimated to have 400 billion suns.
3) The hottest stars such as red giants, do not last very long.
4) The Orion Nebula is 1500 light years from Earth.
5) On Mars, there is a volcano as wide as Arizona and 3 times higher than Mount Everest. This volcano has been named "Mount Olympus".
6) About the Library of Alexandria. It had 10 large research labs, botanical gardens, a zoo, astronomy observatory, a dissection lab. It was the first seriously and systematically collected knowledge of the world.
7) About Eratosthanes and how he figured out the Earth's surface was curved instead of flat.
8) About Hypatia of Alexandria.
9) 15 billion years ago the Big Bang occurred.
