The European Space Agency’s Gaia spacecraft has managed to watch stars tremble, their light subtly changing as starquakes ripple through their surfaces. Which is pretty cool, because Gaia wasn’t even designed to do it.

Let’s say one day astronomers announce that our worst nightmare has come true: a large object is headed towards the Earth with a significant chance of impact. What do we do?

Luke Tipple speaks with Dr. Riley Elliott, a marine biologist from New Zealand who recently tagged baby great white sharks, which are rarely seen in the wild. They talk about how climate change is affecting shark pupping grounds, why fishers are wrong to think there are “too many sharks,” and about Dr. Elliott’s Great White App, which allows users to track great white sharks in the ocean.

Host Luke Tipple is joined this week by renowned Harvard professor, Dr. Avi Loeb, who recently led a deep-sea expedition to discover if evidence for advanced alien life crash-landed off the coast of Papua New Guinea in 2014. They discuss the recent Congressional UFO hearings, how the last seventy years of research into extraterrestrial life has been potentially misguided, and the challenges of searching for tiny objects on the bottom of the ocean.

Luke Tipple is joined by Pulitzer Prize-winning journalist and author of the Outlaw Ocean Ian Urbina, who has dedicated his life to chronicling crime on the high seas. They discuss the state of our world’s oceans, how nearly 20% of your seafood was likely caught illegally, and the surprising link between modern slavery and the killing of sharks.

The discussion turns this week to sharks’ intelligence, and how it varies among species. Host Luke Tipple is joined by Dr. Tristan Guttridge, a behavioral ecologist and veteran of Shark Week whose research has tackled the social smarts, and even personalities, of different kinds of sharks. He sheds light on why we shouldn’t just think of them as dumb fish with rows of razor-sharp teeth. And at the end, our researcher Sierra Kehoe tells us about shark hypnosis.
