For me it was an episode of the Google Cloud Podcast, titled NASA and FDL with James Parr and Madhulika Guhathakurta. It talks about different challenges that we've faced as humans, the steps that we've taken to understand these challenges, and put forward solutions once we understand the data.
It also talks about very valuable data sets of things that we know very little about, hence we have very little data about. Definitely one of the more exciting Google Cloud Podcast episodes.
You can view it at these places, or wherever you get your podcasts!
