How about gifting him a subscription to a podcast app or service such as Spotify or Apple Podcasts? This would give him access to thousands of podcasts and allow him to easily discover new ones. You could also consider a subscription to a specific podcast that he enjoys listening to, or perhaps even a book by his favorite podcaster. If he enjoys discussing podcasts with friends, you could also consider organizing a virtual "podcast club" with his closest friends, gifting them a book and setting up a regular time to discuss it over Zoom.

Or you can get him a star map with an important date you share.
