Is there a way to learn and understand space science and its importance in a more engaging and fun way? The answer is yes. Walkabout the Galaxy helps you grasp complex topics about space science and why it matters in an fun way.

This podcast was started in 2014 by three professors who wanted to share their conversations about science and space discoveries, sometimes touching on science fiction and current events.

Although the show did not attract immediate success, it was worth the big learning curve, leading to the top-quality audio show you can listen to today. The show also caught the attention of WMFE radio, where the professors became regular guests, reaching a broader audience.

James Cooney, Adrienne Dove, and Joshua Colwell prove you should pay attention to what’s happening in the universe. According to the three professors, the show is part of their mission as educators at UCF.

Science news and subversive education about astronomy and science

The Cosmic Companion is a superb podcast on astronomy and science news. This show has no limitations on the subjects discussed. As long as a topic fits the science education ‘bill,’ you will hear it on this podcast. 

About the host: James Maynard grew up around the space program, an origin story from his parents’ meeting while working on the Apollo project, which was designed to land humans on the moon for the first time.

In his podcast, Maynard explores different issues related to the universe and its wonders. He features friendly interviews with writers, scientists, and developers. The topics are primarily about space exploration and advancing knowledge of astronomy, but the pod also touches on other sciences.

Maynard believes in subversive education (teaching people who don’t even know what they want to learn). And he puts it into practice. The Cosmic Companion brings astronomy to you right where you are, proving that we’re all natural-born scientists. This show removes obstacles to learning, helping you rediscover the childhood wonder of the cosmos in a unique educational experience.

Correspondingly, he puts his best foot forward on this podcast to carry the legacy of Carl Sagan, the most famous American astronomer who made the science of the sky available to all. 

The Cosmic Companion is typically delivered in a fun, entertaining manner since memes, comics, and lighthearted videos are thrown into most episodes. Besides, there is an excellent use of technology and storytelling to teach and popularize science education. He plans on spicing things up by bringing the show into the metaverse with interactive 3D environments, including but not limited to a virtual lunar base and a learning center.
