Dr. Michael Marsset and his collaborators use the world's biggest telescopes to image asteroids. They combine those images with other data to get shapes of asteroids. These results are comparable with spacecraft images, but are much less expensive. Dr. Marsset talks about new discoveries they have made using this technique.

Dr Spencer Backus talks about his work at NASA's Jet Propulsion Laboratory. He explains the complexities of trying to design hands for robots. An example of a robot hand is the undersea gripper he worked on, which looks like "an angry starfish." He also talks about the benefits and challenges of in-space assembly of spacecraft.

Dr. Jacob Izraelevitz describes how engineers might design a balloon to explore Venus. This work is in the early stages, what NASA refers to as a "Mission Concept." He also explains the challenges of Venusian exploration.

When taking a sample of the Moon's surface, the Apollo astronauts discovered a sharp transition from powdery soil to harder rock. This transition was entirely unexpected, and remained unexplained for decades. Dr. Ivy Curren talks about an experiment she designed to explain this phenomena. She also tells us about a type of lunar dust formation that scientists call "fairy castle structures."

Mar 24, 2019

Dr. Seager explains how she and other astronomers are looking for extraterrestrial life. We discuss the Drake and Seager equations. We also talk about how astronomers might be able to detect life by measuring chemicals in distant planet atmospheres. This episode is related to the March 2019 National Geographic cover story, "We are not alone."

Mar 10, 2019

Dr. Alicia Lanz talks about the history of astronomical instrumentation, starting with the first telescope. She describes some bizarre historical telescopes and shares a surprisingly inspirational story about bubbles in glass.

Professor Katelyn Allers talks about how you can discover small cold stars! She is a member of the Backyard Worlds project, which is a collaboration between astronomers and citizen scientists. This project searches for brown dwarfs, which are some of the closest objects to our solar system.

Feb 10, 2019

Brent Barbee returns to the show to talk about deflecting asteroids. He explains how an asteroid might react to an impact, and also talks about the proposed DART mission, which would change the orbit of a small asteroid moon.

Jan 27, 2019

Dr. Solange Ramirez returns to the show to talk about her new position as Project Manager of the Sloan Digital Sky Survey V. Amount other things, the project will study over six million stars and how black holes change over time. These millions of measurements will be made using a robotic telescope system that is currently being built.

Jan 13, 2019

Rob Seaman of the Catalina Sky Survey talks about time, and why you need to know the time to discover asteroids and comets. He explains how he installed a highly accurate clock, and makes the case that "natural time" is better than "cold, heartless atomic time."
