As a pioneer in the detection of moons around planets outside our solar system, his work has been published in prestigious scientific journals and has significantly advanced our understanding of distant planetary systems. Kipping employs sophisticated statistical methods to analyze data from NASA's Kepler and TESS missions, extracting subtle signals that reveal the properties of these distant worlds. Beyond academia, he created and hosts the popular Cool Worlds YouTube channel, which has attracted over 750,000 subscribers through its accessible explorations of cosmic frontiers and speculative astronomy. After receiving his PhD from University College London and holding positions at Harvard University, Kipping has established himself as a respected researcher who effectively bridges rigorous scientific investigation with compelling public science communication.
