Sara Seager Explains Exoplanets—S2 Bonus Interview

March 31, 2026·28 min·2 clips

Sara Seager maps the step-by-step scientific path from 'rocky planets exist' to confirming alien life — and explains which step we're currently on.

It starts with the Drake equation. One variable asks what fraction of stars have planets, and exoplanet science has pushed that question from hunch toward evidence. Laura keeps the scale manageable. Exoplanets are planets around stars other than our sun. From there, Sara Seeger talks about what pulled her into the work in the first place. Dark skies did some of it. She remembers a truly dark Idaho sky, the kind that makes space feel less like a diagram and more like a wilderness overhead. Later, astronomy gave that feeling a job title, tying together math, physics, and the night sky in a way she could build a life around. Then the conversation gets into the tools. Kepler shows up as a mission where discoveries often came through data dumps and big analyzed batches, not constant little surprises. TESS changes the pace. The Transiting Exoplanet Survey Satellite releases data quickly, which lets more people join the search if they have the resources and follow-up capacity. Laura stops to unpack the acronym, which helps keep the machinery from getting too far ahead of the listener. James Webb pushes the view further. Seeger describes how different it is from Hubble: infrared, an effectively six-and-a-half-meter mirror, and an orbit more than a million miles from Earth. None of this gets treated like a magic answer box. The telescopes make the search sharper. They do not settle the question. Life may become easier to pin down with evidence, or it may stay rare enough that the search keeps going long after this generation of scientists is done.

As heard by us

A patient exoplanet interview that turns a huge search into something concrete.

Wild Thing uses this bonus interview to trace one line from the Drake equation into the search for exoplanets. The episode moves cleanly from a time when planets around other stars were still mostly a theory to the more concrete era of Kepler, TESS, and James Webb.
