Talking Points

Recent interactions between the hosts and their guests.

April 2026 - Wait, We're How Far Away?
Q: What led you to examine many parameters simultaneously in the ice chemistry models?
We deliberately varied all the key surface parameters at once because many are poorly constrained and we wanted to identify which ones matter most for guiding further quantum chemical or experimental work.
March 2026 - Dude, That Thing is SO OLD
Q: How did you get into astrochemistry to begin with?
Ryan Fortenberry shares a winding path from a love of space and an early fascination with PBS science programming, to choosing physics and computation, meeting mentors, reading foundational astrochemistry texts, and ultimately getting steered toward astrochemistry through collaboration and opportunities at NASA Ames and Virginia Tech.
February 2026 - Anyone Fancy a Space Soda?
Q: Could you explain why this particular molecular cloud is interesting and what it can tell us about astrochemistry as a whole?
The cloud has been a major observational target for a long period, hosting shocks and a relatively low to moderate density regime that promotes complex grain-surface and gas-phase chemistry, leading to many new detections and insights into molecule formation pathways.
February 2026 - Anyone Fancy a Space Soda?
Q: Okay, so just to start out, I'd love to know more about you and your history. How did you get into astrochemistry?
Miguel describes starting in organic chemistry, then shifting to astrochemistry by combining theory, spectroscopy, and observations, eventually focusing on identifying molecules in space and building a holistic view of the chemical landscape.
January 2026 - History, Huh?
Q: Can you tell us about the early days of SETI at Green Bank?
Rebecca described how Frank Drake's Project Osma at the Green Bank Observatory represents the genesis of SETI, detailing the challenges he faced during its inception.
