Across 15,000 generations, human beings have looked out at the sentinel stars and felt the pressing weight of myriad existential questions: Are we alone? Are there other planets also orbiting distant suns? If so, have any of these other worlds also birthed life, or is the drama of our Earth a singular cosmic accident? And what about other minds and civilizations? Have others in the universe, through their success as tool-builders and world-makers, also brought themselves to the brink of collapse?
Remarkably, the first answers to these questions are beginning to arrive. Just as Copernicus reimagined the architecture of our solar system five centuries ago, we are once again in a revolution that pivots on planets. A new science called astrobiology has changed the night sky.

Astrobiology is rewiring our understanding of the intimate connection between life and planets as they appear in the universe.
