648. Rebecca Charbonneau

In this episode, we sit down with historian, Dr. Rebecca
Charbonneau to explore her fascinating new book, Mixed Signals. At
the height of the Cold War, amidst nuclear brinkmanship and deep
political divides, an unlikely collaboration emerged between the
United States and the Soviet Union in the search for
extraterrestrial intelligence. Rebecca dives into the extraordinary
partnership between Ukrainian astrophysicist Iosif Shklovsky and
American astronomer Carl Sagan, whose groundbreaking work in radio
astronomy brought the hunt for alien signals into the scientific
mainstream. From bizarre experiments—like sending the sound of
ballerinas’ movements into space—to navigating the political
tightrope of Cold War diplomacy, this story is as thrilling as it
is thought-provoking. Join us as Rebecca unpacks how the search for
alien life not only opened up new frontiers in science but also
fostered a unique philosophy of international collaboration,
proving that even amidst earthly tensions, humanity could unite in
its curiosity about the cosmos.
