Noam Hassenfeld

Host, Unexplainable

Noam Hassenfeld is the host of Unexplainable, Vox’s science podcast about everything we don’t know. He co-created the show and also composes the music.

Noam particularly loves investigating questions that seem simple — even goofy — at first but lead to surprising places, like “What did dinosaurs sound like?” or “Why do we yawn?” or “What even is sound?”

Before Unexplainable, Noam was a reporter/producer for Today, Explained, where he spent a not insignificant chunk of his time making parody songs about the news. He also co-created the show’s first spinoff series, Today, Explained to Kids, which takes place on the magical (and educational!) Island of Explained.
