Now, thanks to missions like the Kepler Space Telescope, we know that planets are the rule, not the exception. Almost every star in the sky hosts at least one planet. Furthermore, statistical analysis suggests that one in five stars hosts an "Earth-like" planet in the "Habitable Zone"—the Goldilocks region where liquid water can exist. If we are not careful, we will not

The discovery of even a single microbe on Europa or Mars would be the most significant scientific discovery in human history. It would prove that life is not a singular miracle of Earth, but a fundamental function of the universe. If life arose twice in one solar system, it implies the universe is teeming with it.

For millennia, humanity has gazed upward, mesmerized by the glittering arch of the night sky, and asked a singular, defining question: Is anybody out there?

Our best hope for proving we aren't alone lies in —planets orbiting stars outside our solar system. Since the launch of the Kepler Space Telescope and now the James Webb Space Telescope (JWST), we have discovered thousands of these worlds.
