As near as we can tell, our planet is about 4.5 billion years old. It was a wildly inhospitable place in the early eons, with frequent asteroid impacts and a choking atmosphere of carbon dioxide, ammonia, and methane. Yet, life found a foothold after just a few hundred million years, and the chemical reactions that led to the emergence of life are the subject of much research. Scientists from MIT and the Harvard-Smithsonian Center for Astrophysics have undertaken a project to replicate the conditions of Earth four billion years ago, with an emphasis on Earth sciences, in hopes of better understanding the chemical origins of life.
