Many of my other favorites have already been mentioned, but I also listen to:
Twenty Thousand Hertz ("stories behind the world's most
recognizable and interesting sounds")
https://www.20k.org
and have started listening to this new NPR podcast:
Wow in the World ("a new way for families to connect, look up and discover the wonders in the world around them. Every episode, hosts Mindy and Guy guide curious kids and their grown-ups away from their screens and on a journey. Through a combination of careful scientific research and fun, we'll go inside our brains, out into space, and deep into the coolest new stories in science and technology")
