Sidedoor

If you were curating a mixtape that might be heard by aliens billions of years from now - but definitely would be seen by your fellow Earthlings - what would you put on it? In 1977, two Voyager spacecraft launched from Cape Canaveral on a journey that would take them beyond our solar system. Affixed to the side of these two planetary explorers was the Voyager Golden Record — the ultimate mixtape of humanity — containing 27 pieces of music as well as pictures and sounds of Earth. But how did these selections get made? Nearly 50 years later, we're teaming up with our friends at the Smithsonian National Air and Space Museum's podcast, AirSpace, to explore what's on the record, how it got made, and its legacy.Learn more about AirSpace! Airspace Hosts: Matthew Shindell, curator of space history at the Smithsonian's National Air and Space MuseumEmily Martin, planetary geologist at the Smithsonian's National Air and Space MuseumGuests:Ann Druyan, Voyager Golden Record Creative DirectorLawrence Azerrad, Co-founder of Macroscopic

The Curious Case of the Dizzy Kudu. Rhinos with an unexplained skin disease. A lion that could barely chew. Who do you call when there's a mystery at the zoo? The Smithsonian National Zoo and Conservation Biology Institute's anatomical pathologists. These highly-skilled vets search for clues to investigate animal disease and death — sometimes encountering bizarre phenomena. So, grab your microscope and get ready to head through a very special side door of the National Zoo — the necropsy lab. And you're in luck, because pathologist Kali Holder is our guide! Guests:Kali Holder, anatomic pathologist at the Smithsonian's National Zoo and Conservation Biology Institute

From the time we're old enough to hold a crayon, it feels instinctive to draw on the wall. But for MISS CHELOVE – also known as Cita Sadeli – this instinct became a calling. Through bold color and layered symbolism, she transforms everyday public spaces into deeply personal statements, inspiring some passers-by to wonder: what is the role of the public artist? And how can public art both reflect and shape a community's identity?Guests:MISS CHELOVE (also known as Cita Sadeli), independent Washington D.C. - based art director, muralist, designer, and illustrator Sojin Kim, curator for the Smithsonian Asian Pacific American Center's exhibition: Sightlines, Chinatown and Beyond

Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends.

The United States has more martial arts schools than any other country – by far. Chances are you or someone you know practiced karate or another martial art growing up. While martial arts gained popularity in the U.S. for many reasons, one name stands out: Jhoon Rhee. Known as the Father of American Taekwondo, Rhee famously taught Bruce Lee how to kick and Muhammed Ali how to punch. His bare-knuckled American dream made an impact on generations of Americans.Guests: Terence Nicholson, a D.C.-based artist.

A billion-dollar spacecraft, a daring deep-space mission, and one of humanity's biggest questions: Where did we come from? NASA's OSIRIS-REx set out to collect a pristine sample from asteroid Bennu, a cosmic time capsule that may hold clues to the origins of life in our solar system. But the journey was anything but easy.Guests:Erica Jawin, postdoctoral research geologist in the Center for Earth and Planetary Studies at the Smithsonian's National Air and Space Museum and member of the OSIRIS-REx missionTim McCoy, curator of meteorites at the Smithsonian's National Museum of Natural History and deputy mission sample scientist for the OSIRIS-REx missionMike Moreau, deputy project manager in the Space Science Mission Operations Project at NASA's Goddard Space Flight Center 

When we think of serial killers, we tend to think of men—Ted Bundy, Jeffrey Dahmer, Jack the Ripper. But in the 1800s, the deadliest killers often wore corsets. In fact, so many women were arrested for serial poisoning that the era became known as the “Golden Age of Arsenic.” Journey back in time to trace the crimes of Lydia Sherman, a Victorian Era femme fatale who left a trail of bodies in her wake. How did she — and women like her — evade capture for so long? And how did their murders help give rise to modern criminal forensics?Guests: Kristen Frederick-Frost, curator of science at the Smithsonian's National Musuem of American History Lisa Perrin, author and illustrator of The League of Lady Poisoners Deborah Blum, author of The Poisoner's Handbook.

There was a time, before Neil Armstrong set foot on the moon, when some researchers believed women were better suited for space than men. In 1961, a group of female pilots—today known as the Mercury 13—quietly aced NASA's toughest astronaut tests, even outperforming the Mercury men in some areas. But with the space race heating up, their mission was grounded— but not by science. But what became of America's first female astronaut candidates?Guests: Margaret Weitekamp, chair of the space history department at the Smithsonian's National Air and Space Museum, and author of Right Stuff, Wrong Sex: America's First Women in Space Program andSpace Craze: America's Enduring Fascination with Real and Imagined Spaceflight Emily Calandrelli, engineer, author, and TV show host of Emily's Wonderlab and Xploration Outer Space

Whether it's live on the Smithsonian National Zoo's panda cam or in front of a crowd, possibly no other animal's sex life is as closely watched as the giant pandas' is. And there's a reason. These cuddly-looking black and white bears just can't figure out how to mate. But, with a little help from science, the once-endangered giant panda is making a comeback. To honor the arrival of the National Zoo's newest giant pandas, we peep into the (not so secret) sex lives of pandas. Guests: Pierre Comizzoli, panda sex expert and staff scientist at the Smithsonian Conservation Biology InstituteLisa Stevens, AKA “Panda Lady”; former senior curator of mammals at the Smithsonian's National ZooStephen Powers, panda fan

Children say it every day in school, but have you ever wondered why we recite the pledge of allegiance? We journey back to the late 1800s to understand how a massive wave of immigration and sagging magazine subscriptions gave rise to this vow of patriotism. From the Civil War to anti-immigrant nativism and Cold War politics, this one pledge tells many stories. Guests: Debbie Schaefer-Jacobs, curator for the history of education collection at the Smithsonian's National Museum of American HistoryMarc Leepson, author of Flag: An American Biography

"I'm not superstitious, but I'm a little stitious.” As the New Year approaches, this iconic line from The Office feels more relatable than ever. From gulping grapes in Spain to donning yellow underwear in South America and practicing Scotland's ancient “first-footing” tradition, people around the world embrace odd – and oddly meaningful - rituals to ensure good luck in the year ahead. Join us as we travel around the Smithsonian to explore how facing the unknown brings us together at New Year's… in the most unusual ways.Guests:Jim Deutsch, senior content coordinator for America at 250 book project with the Smithsonian Institution, formerly a curator at the Smithsonian Center for Folklife and Cultural HeritageTey Marianna Nunn, associate director of content and interpretation for the Smithsonian's National Museum of the American LatinoTheo Gonzalvez, curator at the National Museum of American HistoryGrace Jan, Yao Wenqing Chinese Painting Conservator at the Smithsonian's National Museum of Asian Art

Sojourner Truth was a women's rights advocate known best for her famous speech "Ain't I a Woman." But Truth never actually said these words. In fact, much of the Truth we know… is fiction. Depictions from different artists and journalists have tweaked Truth's legacy to fit their messages, giving her a “kaleidoscopic reputation,” according to Nell Irvin Painter, author of Sojourner Truth: A Life, A Symbol.  So how did a speech she never gave make Sojourner Truth one of the most famous women's suffragists of the 19th century? And what did Truth actually say? Turns out, the whole Truth is even better than fiction.  Guests: Nell Irvin Painter, author of Sojourner Truth: a Life, a Symbol; Edwards Professor of American History Emerita at Princeton University Ashleigh Coren, former content strategist for the Smithsonian's Our Shared Future: Reckoning with Our Racial Past initiative Kim Sajet, director of the Smithsonian's National Portrait Gallery and host of the Smithsonian's Portraits podcast

Edmonia Lewis was the first sculptor of African American and Native American (Mississauga) descent to achieve international fame. Her 3,000-pound masterwork, “The Death of Cleopatra,” commemorated another powerful woman who broke with convention… and then the sculpture disappeared. On this return episode of Sidedoor, we find them both. You can see "The Death of Cleopatra" at the Smithsonian American Art Museum. The new exhibition, The Shape of Power: Stories of Race and American Sculpture features 82 artworks created between 1792 and 2023, including two by Edmonia Lewis. Guests:Marilyn Richardson, art historian and independent curator Kirsten Pai Buick, professor of art historian at the University of New Mexico and author of Child of the Fire: Mary Edmonia Lewis and the Problem of Art History's Black and Indian SubjectKaren Lemmey, the Lucy S.

Imagine this: invisible robbers break into a bank and steal massive sacks of cash, but instead of running away with it they set their haul on the front stoop of the bank in a glass case. Everyone can see the money, but only the robbers can get to it. That's how IRS Special Agent Chris Janczewski describes the 2016 Bitfinex heist – when mystery hackers made out with over $70 million in Bitcoin. By 2020, their loot had ballooned to over $4 billion. With only digital footprints to follow, federal agents tracked the criminals through the blockchain, across the dark web, and up the service elevator of a posh Manhattan apartment building in a sleuthing story that ends at the Smithsonian. The renovated The Value of Money exhibition will be opening at the National Museum of American History in November 2024.

They carried torches and marched at night. Their goal: defend free speech in America. What started as a small group of young men demonstrating during the 1860 election, snowballed into a mass movement of working-class Americans marching to end slavery. They called themselves the Wide Awakes. And they're widely seen as the political force that helped elect Abraham Lincoln and spur the Civil War. So why has their story gone untold? And why is now the time to tell it?  Guests: Jon Grinspan, Curator of Political History at the Smithsonian's National Museum of American History.

Imagine Jaws without the sneaking tuba. Or Psycho without the shrieking violins. Music can help a horror film strike fear in the heart of theatergoers. And you can trace some of these musical scare tactics back to the era of SILENT films — when organists made up film scores on-the-spot. To celebrate the spooky season this year, we're slashing apart a 1917 silent horror film with composer Andrew Earle Simpson to find out how music can be the beating heart of suspense. Grab your popcorn and get snuggly under the blanket. But be sure to check the closet for a pianist before turning out the lights. Want to see this movie for yourself? Don't miss our live screening of The Devil's Assistant at the National Museum of American History! Join Lizzie, Andrew, and Ryan on Wednesday, October 30th at 7:30pm to see this movie the way it was made to be watched – with live musical accompaniment.

In the Lord of the Rings trilogy, Frodo becomes invisible when he puts the Ring on his finger. Well, at banks in the 1970s, this is basically what happened when a woman put a wedding ring on her finger. Her credit cards would no longer work, and the banks wouldn't count her income as part of the household income. This led to a fight for women's financial independence that gave rise to the landmark Equal Credit Opportunity Act (or ECOA) and the creation of the first women's banks. In honor of the 50th anniversary of ECOA becoming law, we're looking back at a time when women had to have their husband or father cosign on a credit application. What did it take to pass this landmark legislation? And how did it improve women's lives in America?  Guests: Rachel Seidman, curator at the Smithsonian Anacostia Community Museum; curatorial consultant to the Smithsonian American Women's History Museum Emily Card, PhD, author of Staying Solvent: A Comprehensive Guide to Equal Credit for WomenElizabeth Babcock, director of the Smithsonian American Women's History MuseumJeanne Hubbard, former CEO of The Adams National Bank

During the mid-1800s, one third of all paper money in America was thought to be fake. It was the golden age of counterfeiting, and one exceptionally talented con artist stood out from all the rest. His fakes were nearly perfect…but for a trademark tell. Known to law enforcement only as “Jim the Penman,” this celebrity criminal led many Americans to wonder: can great art truly be criminal? GuestsEllen Feingold, curator of the National Numismatic Collection at the Smithsonian's National Museum of American History

Within just a few years, artificial intelligence systems that sometimes seem to display almost human characteristics have gone from science fiction to apps on your phone. But there's another AI-influenced frontier that is developing rapidly and remains untamed: robotics. Can the technologies that have helped computers get smarter now bring similar improvements to the robots that will work alongside us? In this episode of The Joy of Why podcast, Daniela Rus, a pioneering roboticist at the Massachusetts Institute of Technology, talks to host Steven Strogatz about the surprising inspirations from biology that may help robots rise to new levels. Subscribe to The Joy of Why from Quanta Magazine wherever you listen to podcasts! 

There aren't many portrait artists who get recognized on the street, but it happens to Devon Rodriguez all the time. After quietly honing his skill for a decade, Devon started posting videos of his live drawings of New York City subway commuters to social media. The videos took off, earning him some 50 million followers and placing portraiture in front of a huge new audience.In this episode of the Smithsonian's National Portrait Gallery's podcast, Portraits, Director Kim Sajet speaks with Devon about the mentors who had his back, and this new model for showing art— not in museums, but on screens.See the portraits we discussed:Kim Sajet, by Devon RodriguezJohn Ahearn, by Devon Rodriguez“The Rodriguez Twins,” by John AhearnMaría Elena Estrada, by Devon RodriguezDevon Rodriguez draws Kim Sajet, Instagram

In the twentieth century, the jetpack became synonymous with the idea of a ‘futuristic society.' Appearing in cartoons and magazines, it felt like a matter of time before people could ride a jetpack to work. But jetpacks never became a mainstream technology, leaving many to wonder…why? In this episode of 99 Percent Invisible, producer Chris Berube travels to the Udvar-Hazy Center of the Smithsonian's National Air and Space Museum to find out for himself.This episode was produced by Chris Berube. He spoke with Bill Suitor, Don Erwin, and the Smithsonian's Colleen Anderson. David Taylor reported on the rocket belt for The Washington Post in 2022, and Steve Lehto wrote about the belt, and other jetpack technology, in his book The Great American Jetpack.Transcript available here: https://99percentinvisible.org/episode/rocket-man/transcript/

It's been called ‘the most noble and absurd undertaking ever attempted by any state.' During the height of the Great Depression, the U.S government hired out-of-work writers and laid-off reporters and sent them out to record the stories of all kinds of Americans. Called the Federal Writers' Project, historians have called the program a giant “listening project.”While on our summer break, we're sharing the first episode of a new podcast series called The People's Recorder. Host Chris Haley sets the stage, laying out 1930s America, the New Deal, and the cultural forces that both supported and opposed the Writers' Project. The project of holding up to America raises questions: What history gets told? And who gets to tell it? You can listen to rest of the series by searching for The People's Recorder wherever you get your podcasts.

For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep's wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why? Today, the only known pelt of this extinct breed is in the collections of the Smithsonian's National Museum of Natural History, and it might hold some answers. Through collaborate research combining Western science with Indigenous knowledge, we delve into this animal's genome to learn the real story of the woolly dog's disappearance. Guests:Audrey Lin, evolutionary molecular biologist, research associate at the Smithsonian's National Museum of Natural History and postdoctoral scholar at the American Museum of Natural HistoryLogan Kistler, curator of archaeobotany and archaeogenomics in the anthropology department of the Smithsonian's National Museum of Natural History Liz Hammond-Kaarremaa, master spinner who studies traditional Salish textiles as a research associate at Vancouver Island University and the Smithsonian's National Museum of Natural HistorySteven Point / Xwĕ lī qwĕl tĕl, grand chief of the Stó:lō Tribal Council, chancellor of the University of British Columbia, former lieutenant-governor of British Columbia, retired judge, and member of the Skowkale First NationDebra Sparrow / θəliχʷəlʷət, weaver, artist and knowledge-keeper from Musqueam.

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.

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

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.

Money is power. But who's on our money - or isn't - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn't until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide whose likeness gets engraved in our national story? And who makes these decisions? We'll follow the money to find out.
