The Rock 50 Light-Years Away
What if you could tell whether a rock exists on a planet 50 light-years away — without ever leaving Earth? This week Chris and Jesse welcome back friend-of-the-show Dr. Jackie Faherty (American Museum of Natural History) for her fourth appearance to talk about one of the wildest results in exoplanet science yet. The crew digs into a new Nature Astronomy paper on a rocky planet about 30% larger than Earth, orbiting a tiny star, whipping around fast with a scorching ~1,000 Kelvin surface and — ...

The Room Problem (and how Geochronology solves it)
Granite is everywhere — it makes up much of the continental crust beneath our feet; yet, for over a century geologists were stuck on a deceptively simple question: where does all that magma find room? In this episode, Jesse and Dr. Mike Ackerson pick the granite series back up to tackle the "room problem" — the puzzle of how you wedge a magma body tens of kilometers wide into solid crust. Using California's Tuolumne Intrusive Suite (the fruit fly of igneous petrology) and the landmark Coleman...

Rocks for the Future - with MIT Prof. Oli Jagoutz
What does cracking open green-shiny rocks in a German preschool have to do with feeding eight billion people without oil and gas? In this episode, Jesse sits down with Oliver "Oli" Jagoutz, professor at MIT and director of the Earth Resources Laboratory (ERL), for a wide-ranging conversation that travels from the Himalayas to the wastewater treatment plant — and makes the case that geology might be one of the most societally relevant sciences of the coming decades. Oli traces his winding path...

The Fundamentals of Geology (Exam)
This week we take on the FG test — the Fundamentals of Geology exam — the very first step on the road to becoming a professionally licensed geologist. Jesse just sat the exam this past fall (yes, a geology professor going back to take Geology 101), and we get into exactly what that was like: the nerves, the cram sessions, and the very real fear of an embarrassing fail. We break down what's actually on the ASBOG FG exam — 110 multiple-choice questions across eight content domains, from general...

Granite Wars: The Debates That Built a Science
In this episode, we sit down with Dr. Mike Ackerson (Smithsonian) for the kick-off of a deep-dive series on granites and granitoids. This one goes into the weeds: the 250-year history of how arguing about granite shaped nearly every major idea in the geosciences. We trace the great controversies from the 1700s to today: 🌊 Neptunism vs. Plutonism — Did granite precipitate out of a global ocean, or crystallize from molten rock? How James Hutton's fingers of granite at Glen Tilt helped kill the ...

The Geologist's License: How the FG and PG Exams Get Built — with Keith Rapp
In this episode, we sat down with Keith Rapp, senior hydrogeologist, longtime volunteer with ASBOG (the Association of State Boards of Geology), and immediate past president of the organization. We dug into the professional geologist licensure process — what the FG (Fundamentals of Geology) and PG (Practice of Geology) exams actually test, how questions get written and vetted by panels of subject matter experts, why some states require licensure and others don't, and why Keith argues that lic...
