The Chemistry of Life: Why Phosphorus and Nitrogen Rule the Stars

Ultimately, this research serves as a reminder of the staggering complexity of life. It underscores the idea that habitability is a multi-layered puzzle, involving physics, orbital mechanics, and—most importantly—deep-seated chemistry. As we move forward with advanced telescopes like the James Webb, we must look beyond the surface level. We must seek out worlds that possess the right internal ingredients to foster a biological revolution, ensuring that we don't spend our time chasing "pointless" planets that have the water for life but none of the tools to build it.
