The Discovery of Pluto: A Search for [Deep Dive] - February 18th, 2026

On February 18th, we explore a day marked by profound scientific discovery and immense moral courage. The core of today's episode centers on the 1930 discovery of Pluto by Clyde Tombaugh, an event that concluded the long-standing search for 'Planet X' and expanded our map of the solar system. We also delve into the heavy history of the White Rose resistance, specifically the 1943 arrest of Sophie Scholl, whose defiance against the Nazi regime remains a beacon of human integrity. Additionally, we celebrate the birthdays of three cultural and scientific giants: Alessandro Volta, the inventor of the electric battery; Toni Morrison, the Nobel Prize-winning novelist who transformed American literature; and Dr. Dre, the visionary producer who redefined hip-hop. From the icy reaches of space at the Lowell Observatory to the high-stakes activism at the University of Munich, this episode of Deep Dive examines how individual actions and insights continue to resonate through history.

February 18th serves as a powerful reminder of how individual conviction and scientific persistence can reshape our world. In 1930, American astronomer Clyde Tombaugh identified Pluto at the Lowell Observatory in Flagstaff, Arizona, resolving a decades-long hunt for a theoretical ninth planet and sparking a legacy that continued through its 2006 reclassification. The day also carries a solemn weight, marking the 1943 arrest of Sophie Scholl and the White Rose resistance members by the Gestapo for their distribution of anti-Nazi leaflets. Their bravery in the face of certain execution stands as a testament to moral resistance. Beyond these milestones, we honor the legacies of physicist Alessandro Volta, literary icon Toni Morrison, and hip-hop architect Dr. Dre. These figures represent the intersection of scientific innovation, cultural mastery, and the unyielding human spirit.
