Spacepod

Hear stories about the alien moons orbiting other planets, of cold stars, and the future of space exploration. Every week, Dr. Carrie Nugent chats about an amazing part of our universe with a scientist or engineer. Spacepod is the podcast that gives you an inside look into space exploration and astronomy.

Professor Jay McMahon stops by the show to explain the YORP effect and how it changes asteroid spins and shapes. He also describes his NASA Institute for Advanced Concepts (NIAC) project that is investigating the use of soft robots to explore rubble-pile asteroids.

Aug 27, 2017

Dr. Mary Peterson tells us about basaltic glasses from the Galápagos Islands, and why they might have originated deep within the Earth’s mantle. She also describes her lab work, which involves cool lab coats, security badges, and meticulous sorting of samples.

Aug 13, 2017

Dr. Andrea Donnellan stops by the show to talk about GeoGateway, a website that combines different datasets to help geologists. She explains how rocks move like silly putty, and recounts the time a lone cloud masqueraded as tectonic motion.

Bonus music at the end is “Glorious Dawn” by Colorpulse. Hear more rad science tunes at www.symphonyofscience.com.

Jul 30, 2017

Dr. Emily Kramer stops by the show to try some tea and talk about her trip to South Africa to observe the next New Horizons target, 2014 MU69. She was one of several astronomers and planetary scientists who flew to other countries to watch this object pass in front of a star in the hopes of measuring its diameter.

Jul 16, 2017

Dr. Quan-Zhi Ye tries an unusual frappuccino and explains how meteor showers are related to comets. He tells the story of how he became interested in comets and asteroids, and fills us in on some of his recent research.

Jul 2, 2017

Dr. Jessie Christiansen returns to the show to talk about newly discovered exoplanets! She explains why this planetary system was devilishly difficult to observe with ground-based telescopes, and how one of the planets poses a puzzle.

Jun 18, 2017

Dr. Raymond Francis talks about a rock-vaporizing laser and the software that controls it. He describes how he and colleagues programmed a computer to make choices like a geologist would, allowing the Curiosity rover to do more science on Mars.

Jun 4, 2017

Dr. Bethany Ehlmann returns to talk about Ceres. She tells us what certain types of silicates have in common with phyllo dough, and explains how traces of ammonia on Ceres hint at unusual history for this dwarf planet.

May 28, 2017

Dr. Tiffany Meshkat describes direct imaging of exoplanets, which astronomers have used to discover enormous, young planets. She also talks about WFIRST, a mission under development that would be able to find and characterize exoplanets.

May 21, 2017

Dr. Armando Azua-Bustos talks about how he discovered the driest place on Earth— a region in the Atacama Desert not far from where he grew up. He explains how he collects and studies microbial life that live in these extremely dry regions.

May 14, 2017

Dr. Michele Koppes stops by to talk about her glacier research on planet Earth. She describes how a melting glacier triggered a staggeringly large landslide in 2015, and how glaciers can match even humans in their ability to transform the landscape.

May 7, 2017

Dr. David Ciardi talks about Vega, a bright star that’s “been a part of human lore forever.” Dr. Ciardi and his colleagues discovered that Vega has a nearby ring of dust, implying the presence of planets. He also describes an encounter with a giant inflatable bumblebee at Palomar Observatory.

Apr 30, 2017

John Dailey explains how he uses his software engineering skills to discover asteroids at IPAC/Caltech. He helps solve problems inherent to working with astronomical data, such as the challenge of reading in and out huge volumes of data from hard drives.

Apr 23, 2017

Dr. Ingrid Daubar stops by to talk about HiRISE, a camera on a Mars-orbiting spacecraft that takes amazing images of the Martian surface. She explains how she uses these images to search for fresh craters, and how you (yes you!) suggest areas of the planet for this camera to image. (Correction to episode: Mars’ atmosphere is 0.6% that of  Earth, not 6%)

Apr 16, 2017

Marta Bryan shares her new results on exoplanets! She explains how she tested a theory of hot jupiter formation, and how she figured out that planet rotation rates are likely set early on in the planet’s lifetime.

Apr 9, 2017

Dr. Rahul Patel describes his search for undiscovered disks of dust around other stars. He explains how looking for fainter and fainter debris disks may bring us closer to discovering a planetary system similar to our own.

Apr 2, 2017

Dr. Ivy Curren talks about Mars’ moon Phobos, and how grooves on its surface indicate that the interior may be fractured. This small, mysterious moon is covered in faults, making it a dicey place for future missions to land.

Mar 26, 2017

Dr Roberta Paladini talks about the space-based Herschel Space Observatory, which was the largest infrared telescope ever launched. It looked at the sky in the far infrared, and discovered an abundance of water in star-forming regions.

Mar 19, 2017

Dr. Andy Thompson explains how he uses robotic ocean gliders to learn about our planet. He tells us how ocean water interacts with the atmosphere, and how parcels of water can preserve information about that interaction for thousands of years.

Mar 14, 2017

As part of the 2016 TED Fellows class, I got to meet cool people and I got to talk about asteroids. My TED talk is now online on www.TED.com (check it out!) and the companion book, “Asteroid Hunters”, by me, is now available in the US, UK, Canada, Australia, and India. There’s also e-book and audiobook versions. This bonus episode contains an excerpt from “Asteroid Hunters”.

Mar 12, 2017

Dr. Erin Burkett tells us what prairie dog research has to do with an earthquake early alarm system. She also talks about how to motivate people to prepare for earthquakes, and emphasizes the importance of storytelling in science communication.

Mar 5, 2017

Dr. Robert Hurt returns to the show to talk about artistic depictions of interstellar travel. We discuss the images of the seven-planet TRAPPIST-1 system he and Tim Pyle created— images that graced the cover of Nature and the front page of the New York Times. We also talk about Star Trek: The Next Generation, and what that TV show got right (and wrong) about the visuals of cruising through outer space.

Feb 26, 2017

Professor Mansi Kasliwal talks about the GROWTH project, which uses international teamwork to watch astronomical events around the clock. An individual observer is thwarted by sunrise, but together, an international team can continuously monitor supernovae, neutron stars, and asteroids over 24 hours.

Feb 19, 2017

Dr Linda Billings talks about the importance of clear communication across the expert/non-expert boundary. She describes the difference between the words “risk”, “hazard” and “threat,” as applied to near-Earth objects and gives advice to scientists who want to communicate their research accurately.

Feb 12, 2017

Dr. Marcia Burton stops by the show to talk about radio waves from Saturn, as measured by the Cassini Spacecraft. We listen to some audio clips, and she explains why it is so difficult to measure the length of Saturn’s day.
