Hosted by Neil deGrasse Tyson, StarTalk Radio harmonizes Pop Culture and science related topics by discussing them with humor and passion.  Popular topics include the Big Bang, superheros, and breaking news in the world of science.  He is joined each week by a comedian co-host, celebrities, and other special guests.

When asked what specific topics will be explored, Tyson said: "Everything under the sun; Or rather under the universe!" He continued by saying his audience would be "All the people who never knew how much they’d love learning about space and science."


Science... Sort Of 
A group of scientists from a wide range of backgrounds discuss science, things that are sort of science, and "things they wish were science."  Check out their film commentary for Jurassic Park featuring a paleontologist!

Remember that amazing publication with the feast-for-your-eyes photos?  They make a podcast now!  This podcast is released in tandem with their weekly publication.

"Skeptoid is a weekly science podcast dedicated to furthering knowledge by blasting away the widespread pseudosciences that infect popular culture, and replacing them with way cooler reality.

Each weekly episode focuses on a single phenomenon — an urban legend, a paranormal claim, alternative therapy, or something just plain stupid — that you've heard of, and that you probably believe in. Skeptoid attempts to expose the folly of belief in non-evidence based phenomena, and more importantly, explains the factual scientific reality."

99% Invisible
This podcast reveals topics that effect our daily lives but remain under the radar, or as the title suggests, 99% Invisible.  Wonderfully produced, topics range from the loss of perfect security, the color of money, to PDX carpet.

Science Friday
This weekly podcast brings you up to date with what is new in science and a few other topics you may not have heard about. 

If you haven't heard of Radiolab, we envy the next several weeks you'll spend listening to these podcasts for the first time.  A feast for the ears, Radiolab uses interviews, sound bites, and soundscapes to delve into topics that excite your brain.  A few of my favorites from this podcast are 'Finding Emilie,' 'Colors,' and 'This is Your Brain on Love.'
