We've wanted to up our stoke recently, so after a lot of consideration, we decided to launch a three part series on PLANETS. We love em. We love em a lot!! Heck, we better, cuz we live on one!! In this first part of our series on planets, we talk about what we know, how we know it, why we care so much, the history of our motivation to explore, and what we know about Earth. We bump into a lot of interesting crossover between astronomy, the scientific method, and the history of humanity's scientific exploration. Expect to get a little choked up in this episode. Our history is amazing, our exploration is inspiring, and "the void" is physically, intellectually, and spiritually challenging. In parts II and III we'll venture off-world into our solar system, and eventually out into the cosmos.
