It's easy to feel overwhelmed by all the podcast options out there, but narrowing down your choices to the titles that will teach you something while you listen is a good place to start. If you're interested in learning more about philosophy, science, linguistics, or history, here are podcasts to add to your queue.
1. THE HABITAT
The Habitat is the closest you can get to listening to a podcast recorded on Mars. At the start of the series, five strangers enter a dome in a remote part of Hawaii meant to simulate a future Mars habitat. Every part of their lives over the next year, from the food they eat to the spacesuits they wear when they step outside, is designed to mimic the conditions astronauts will face if they ever reach the red planet. The experiment was a way for NASA to test plans for a manned mission to Mars without leaving Earth. The podcast, which is produced by Gimlet media and hosted by science writer Lynn Levy, ends up unfolding like a season of the Real World with a science fiction twist.
2. STUFF YOU SHOULD KNOW
Can’t pick a topic to educate yourself on? Stuff You Should Know from How Stuff Works is the podcast for you. In past episodes, hosts Chuck Bryant and Josh Clark (both writers at How Stuff Works) have discussed narwhals, Frida Kahlo, LSD, Pompeii, hoarding, and Ponzi schemes. And with three episodes released a week, you won’t go long without learning about a new subject.
3. THE ALLUSIONIST
Language nerds will find a kindred spirit in Helen Zaltzman. In each episode of her Radiotopia podcast The Allusionist, the former student of Latin, French, and Old English guides listeners through the exciting world of linguistics. Past topics include swearing, small talk, and the differences between British and American English.
4. PHILOSOPHIZE THIS!
Listening to all of Philosophize This! is cheaper than taking a philosophy class—and likely more entertaining. In each episode, host Stephen West covers different thinkers and ideas from philosophy history in an approachable and informative way. The show proceeds in chronological order, starting with the pre-Socratic era and leading up most recently to Jacques Derrida.
5. MORE PERFECT
In 2016, Radiolab, one of the most popular and well-established educational podcasts out there, launched a show called More Perfect. Led by Radiolab host Jad Abumrad, each episode visits a different Supreme Court case or event that helped shape the highest court in the land. Because of that, the podcast ends up being about a lot more than just the Supreme Court, exploring topics like police brutality, gender equality, and free speech online.
6. SLOW BURN
The Watergate scandal was such a important chapter in American history that it has its own suffix—but when asked to summarize the events, many people may draw a blank. Slow Burn, a podcast from Slate, gives listeners a refresher. In eight episodes, host Leon Neyfakh tells the story of the Nixon’s demise as it unfolded, all while asking whether or not citizens would be able to recognize a Watergate-sized scandal if it happened today.
7. LETTERS FROM WAR
Instead of using a broad scope to examine World War II, the Washington Post podcast Letters From War focuses on hundreds of letters exchanged by four brothers fighting in the Pacific during the period. Living U.S. military veterans tell the sibling's story while reflecting on their own experiences with war.
8. LEVAR BURTON READS
Just because you’re a grown-up doesn’t mean you have to miss out on the soothing sound of LeVar Burton’s voice reading to you. The former host of Reading Rainbow now hosts LeVar Burton Reads, a podcast from Stitcher aimed at adults. In each episode, he picks a different piece of short fiction to narrate: Just settle into a comfortable spot and listen to him tell stories by authors like Haruki Murakami, Octavia Butler, and Ursula K. Le Guin.
9. BRAINS ON!
Brains On! is an educational podcast for young audiences, but adults have something to gain from listening as well. Every week, host Molly Bloom is joined by a new kid co-host who helps her explore a different topic. Tune in for answers to questions like "What makes paint stick?" and "How do animals breathe underwater?"
10. SCIENCE VS
There’s a lot of misinformation out there—if you’re determined to sort out fact from fiction, it can be hard to know where to start. The team of “friendly fact checkers” at the Science Vs podcast from Gimlet is here to help. GMOs, meditation, birth control, Bigfoot—these are just a few of the topics that are touched upon in the weekly show. The goal of each episode is to replace any preconceived notions you have with hard science.
11. FLASH FORWARD
No one knows for sure what the future holds, but Flash Forward lays out the more interesting possibilities. Some of the potential futures that host and producer Rose Eveleth explores are more probable than others (a future where no one knows which news sources to trust isn’t hard to imagine; one where space pirates drag a second moon into orbit perhaps is), but each one is built on real science.
12. HIDDEN BRAIN
What motivates the everyday choices we make? That’s the question Shankar Vedantam tries to answer on the NPR podcast Hidden Brain. The show looks at how various unconscious patterns shape our lives, like what we wear and who we choose to spend time with.
13. PART-TIME GENIUS
The fact that it’s hosted by Mental Floss founders Will Pearson and Mangesh Hattikudur isn’t the only reason we love Part-Time Genius. The podcast from How Stuff Works wades into topics you didn’t know you were curious about, like the origins of Nickelodeon and the hidden secrets at the Vatican. Each episode will leave you feeling educated and entertained at the same time.
14. ASTRONOMY CAST
It’s a big universe out there—if you want to learn as much about it as possible, start with Astronomy Cast. Fraser Cain, publisher of the popular site Universe Today, and Dr. Pamela L. Gay, director of the virtual research facility CosmoQuest, host the podcast. They cover a wide range of topics, from the animals we’ve sent to orbit to the color of the universe.
15. SCIENCE OF HAPPINESS
The Science of Happiness podcast from PRI is here to improve your life, one 20-minute episode at a time. Science has proven that adopting certain practices, like mindfulness and gratitude, can make us happier—as does letting go of less unhealthy patterns like grudges and stressful thinking. With award-winning professor Dacher Keltner as your host, you can learn how to incorporate these science-backed strategies for happiness into your own life.
