Join us as we journey across the cosmos with astronomer David Reneke to uncover the secrets of comets, asteroids, and the origins of life. In this episode, we explore a rare interstellar comet, 3I/ATLAS, carrying molecules linked to organic chemistry, samples from asteroid Ryugu revealing the building blocks of DNA and RNA, and a newly discovered comet C/2025 R3 (PanSTARRS) that could be visible from Earth in April 2026..

David takes us from distant star systems to our backyard skies, showing how studying space objects helps unravel the history of life and our Solar System.
