Cosmic Journey I: "Stellar Buffoonery"

Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and rejected by his scientific community.

This is the first episode of a two-part journey celebrating the 25th anniversary of the Chandra X-ray Observatory and the Smithsonian Astrophysical Observatory's operation of the space telescope.

Join us this summer for a cosmic journey full of events and virtual resources from around the Smithsonian that will transport you from our closest star, the sun, to the far reaches of the universe. Find the full schedule on our website, si.edu/cosmicjourney. Or follow along on social media @Smithsonian.

Guests:

Kim Arcand, Visualization Scientist and Emerging Tech Lead for NASA's Chandra X-ray Observatory at the Smithsonian Astrophysical Observatory

Priyamvada Natarajan, astrophysicist and professor at Yale University

Arthur I. Miller, author of "Empire Of The Stars: Obsession, Friendship, and Betrayal in the Quest for Black Holes"

Cicadapalooza

Thecicadas are back for some fun in the sun, and this time, they’re louder than ever! For the first time since 1803, Broods XIII and XIX will be emerging at the same time, covering the American South and Midwest with trillions ofcicadas. As Smithsonian entomologist Floyd Shockley readies his nets for the biggest bug invasion in centuries, we look back at the emergence of Brood X in 2021, and explore howcicadas have captivated our human ancestors for millennia.

Guests:

Floyd Shockley, entomologist at the Smithsonian’s National Museum of Natural History

Gao Hong, professional pipa player, composer, and educator

Jim Deutsch, curator at the Smithsonian Center for Folklife and Cultural Heritage

Jan Stuart, Melvin R. Seiden Curator of Chinese Art at the Smithsonian’s National Museum of Asian Art

The Birds and the Beans

"God in a cup." "Perfection." "The world's best coffee." Panamanian geisha coffee has been called many things, but never Smithsonian Bird Friendly certified. That might soon change, however, as researchers from Smithsonian National Zoo and Conservation Biology Institute’s Migratory Bird Center find new ways to grow coffee in harmony with migratory songbirds. Join us for this fully caffeinated romp through Panama’s coffee farms as we learn all about the birds and the beans.

Guests:

Ruth Bennett, research ecologist at the Smithsonian National Zoo and Conservation Biology Institute’s Migratory Bird Center

Katherine Araúz Ponce, fellow at the Smithsonian Tropical Research Institute and PhD student at The University of Georgia

Maria Ruiz, owner of Ruiz Coffee Distributors

Ratibor & Aliss Hartmann, owners of Finca Hartmann, specialty coffee and ecotourism

Price Peterson, owner of Hacienda La Esmeralda

Dude, Where’s my Carbon?

If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along to see how carbon is measured, and why so much ends up in tropical forests.

Guests:

Joshua Tewksbury, director of the Smithsonian Tropical Research Institute in Panama

Helene Muller-Landau, senior scientist at the Smithsonian Tropical Research Institute researching tropical forests and ecosystems, leader of ForestGEO Global Carbon Program

David Mitre, research manager for ForestGEO at the Smithsonian Tropical Research Institute

Sergio dos Santos, project manager for the Smithsonian Tropical Research Institute’s Hydro-Meteorological and Oceanographic Monitoring Program in Panama

Luisa Fernanda Gómez Correa, intern at the Forest Carbon Lab at the Smithsonian Tropical Research Institute

Eline De Loore, graduate student at Ghent University conducting research at the Smithsonian Tropical Research Institute

Monkeyin' Around on the Devil's Island

It started as a rumor in the cafeteria of the Smithsonian Tropical Research Institute in Panama: monkeys on an island in the Pacific were doing something no one had ever seen them do before. But when researchers went searching for these elusive capuchin monkeys, they discovered more questions than answers.

Guests:

Claudio Monteza, Smithsonian Tropical Research Institute fellow and researcher at the Max Planck Institute of Animal Behavior

Brendan Barrett, researcher at the University of Konstanz and theMax Planck Institute of Animal Behavior

Meg Crofoot, director of the Department for the Ecology of Animal Societies at the Max Planck Institute of Animal Behavior. Former Smithsonian Tropical Research Institute fellow
