200: Pluto is a planet, and so is its moon with Dr. Runyon
Dr. Kirby Runyon shares his definition of "planet"-- a round celestial body that was never a star. Using this definition, there are over 150 planets orbiting our sun. He explains why the word planet matters, and why little planets might be the most common planets in our universe.

199: Why can't we find Planet Nine with Prof. Lawler
Professor Lawler discusses why planet nine might not exist. She explains why reporting not finding something is as important as reporting a discovery. She tells us how satellite internet is getting in the way of astronomical observations.

198: Dragonfly with Dr. Turtle
Dr. Zibi Turtle is the Principal Investigator of NASA's Dragonfly mission. She tells us what it is like to design and build an octocopter that will roam the surface of Saturn's moon Titan. She also tells us about Titan's exciting chemistry.

197: A massive asteroid hit at tremendous speed with Prof. Richardson
Professor Derek Richardson gives us an update on the DART mission, which is headed towards tiny asteroid moon Dimorphos. If all goes well this fall, DART will crash into Dimorphos at four miles per second! This experiment will be a test of asteroid deflection technology.

196: Spinning universe with Dr. Cheng
Dr. Jon Cheng tells us about his fluid flow experiments. These experiments investigate fundamental physics. They can be applied to the movement of the Earth's core as well as things like liquid batteries. Is electro-vortex flow the coolest phrase said on the show yet? Listen and decide!

195: Dark and quiet skies with Dr. Rawls
Dr. Meredith Rawls talks about the unintended consequences of artificial satellite constellations. Satellites change the night sky, impacting the people and animals that rely on it. Hundreds of thousands of these satellites may be launched, which could create more orbital debris and endanger future space missions. She explains how people are coming together to help fix this problem.

194: Exoplanet next door with Prof Whitten
Prof Jenny Whitten tells us about VERITAS, a NASA mission that will orbit Venus. She explains how scientists will use radar to learn about the surface, and how they picked exactly which radar band to use. She also talks about how VERITAS will shed light on Venus' evolution, the history of water on the planet, and its geologic processes.

193: Orbital parking spots with Larissa Markwardt
Larissa Markwardt talks about Trojan asteroids-- asteroids that orbit the sun a little before or after planets. She describes the special technique she uses to find these asteroids, and why not finding any is an interesting result.

192: Craters on Titan with Prof. Neish
Professor Catherine Neish explains why there's so few craters on Saturn's moon Titan. She explains why Titan's craters may contain the organic molecules needed for life, and how the Dragonfly mission will test that hypothesis.

191: Back to Venus with Dr. Getty
Dr. Stephanie Getty tells us about DAVINCI, which will go to Venus. DAVINCI will scan the planet during three flybys, and will deploy a probe. She explains how engineers will protect the probe's instruments from Venus' harsh environment, and how you can't build a spacecraft without meetings and emails.

190: Millions of observations with Dr. Spoto
Dr. Federica Spoto tells us how she found millions of high-precision observations of comets and asteroids. She explains how these observations let her turn back time and study the history of the main belt of asteroids in our solar system.

189: Long Range Planning with Prof. Barmby
Professor Barmby tells us how a group of astronomers created the Canadian Astronomy Long Range Plan. This plan outlines the priorities of Canadian astronomers for the next decade. It covers telescopes, computing resources, diversity and inclusion in astronomy, and the need to consider the environmental consequences of astronomy.

188: Failing is the most important part of science with Tyler Linder
Planetary defense researcher Tyler Linder talks about the benefits of using automated telescopes. He tells us the difference between an automated and a robotic telescope, and explains that inexpensive telescope time lets students learn, experiment, and fail. He describes the work he does with students, and why it is important to him.

187: You doubt your own existence with Prof. Méndez
Prof. Abel Méndez tells us about his Planetary Habitability Lab. He talks about the chances of discovering extraterrestrial life, explaining that we are "alone by isolation and distance." He also tells us about his team's Visible Paleo-Earth project, as well as the proposed plans to rebuild the Arecibo Radio Telescope.

186: What's more powerful than a dinosaur with Dr. Noviello
Dr. Jessica Noviello tells us a story about the power of interdisciplinary science: the time geologists, physicists, archeologists, chemists, paleontologists, and petroleum engineers all came together to solve a big mystery. This story focuses on a layer of clay that divides the "dinosaur part of time" from the "non dinosaur part of time."

185: Solar system snapshots with Kevin Gill
Kevin Gill explains how he transforms raw spacecraft images into stunning planet photos. He describes how he turns black and white images from the Juno spacecraft into full color mosaics of Jupiter. He also tells us about his experiences with the "King of Cameras" on Cassini.

184: Samples are forever with Prof. Snead
Prof. Christopher Snead tells us how he is preparing a very clean laboratory. In this lab, scientists will store and study Hayabusa-2 mission asteroid samples. The samples will be photographed and manipulated without ever touching Earth's atmosphere.

183: The solar wind with Dr. Jian
Dr. Lan Jian talks to us about the solar wind, which is ionized gas from the sun. It transfers energy from the sun to the planets, and can impact astronauts and technology. She shares her research, which includes interpreting data from spacecraft and computer modeling.

182: Radar polarization with Dr. Hickson
Dr. Dylan Hickson talks about how he studies the surfaces of asteroids using reflected radio waves. By comparing the reflections to mathematical models and data from Earth, he tries to determine if an asteroid's surface is blocky, dusty, or both.

181: Young Stellar Objects with Dr. Smith
Dr. Rachel Smith tells us about her research into young stellar objects. These new stars are surrounded by a cloud of dust that may eventually become planets. Dr. Smith also explains why she thinks it is important to physically travel to telescopes when she makes her observations.
