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.

Feb 5, 2017

Dr. Luisa Rebull explains why it is vital to archive astronomical images. NASA archives, such as the ones at IPAC, are accessible everyone on Earth at no cost. Luisa also describes how you can take a tour through archived data via the Dustier, Messier, Messier Marathon.

Jan 29, 2017

Eric Christensen, head of the Catalina Sky Survey, talks about how he and his team hunt asteroids and comets. He explains how astronomers can distinguish between individual asteroids and how new upgrades will let the survey discover more asteroids than ever before.

Jan 22, 2017

Dr Jeff Rich stops by the show to talk about variable stars. Some variable stars change brightness dramatically over several hours, and certain types can be used to measure distances. Jeff also explains what it’s like to propose for, and get, time on the Hubble Space Telescope.

Jan 15, 2017

Brother Guy Consolmagno shares a Coke and talks about the Vatican Observatory, a discovery that got him in trouble with the Voyager team, and why being next to a dairy farm was convenient when he wanted to measure the properties of meteorites.

Jan 8, 2017

Dr. Norna Robertson shares a drink from her home country and talks about a specific part of LIGO. She explains that LIGO’s eighty-pound mirrors are suspended by four, incredibly thin, silica fibers that were developed just for this project.

Jan 1, 2017

Dr. Kanner explains how gravitational waves could teach us about the big bang, and how we might be on the cusp of discovering new phenomena that are so unusual, theorists haven’t even predicted their existence.

Dec 25, 2016

Dr. Kanner talks about gravitational waves, which were detected for the first time by LIGO last year. He explains how studying neutron stars with gravitational waves can tell us how everyday elements like gold came to be.  

Dec 18, 2016

Dr. Abby Fraeman returns to the show to talk about Opportunity, the rover that won’t quit. Along with its sister rover, Spirit, Opportunity has discovered Mars rocks that could have only formed in the presence of water.

Dec 11, 2016

Eric Rice talks about systems engineering and we drink what turns out to be the most disgusting beverage yet. He talks about what it is like to control a spacecraft, and explains why predicting what can go wrong with a spacecraft is a lot simpler than predicting what can go wrong at a wedding.

Dec 4, 2016

Dr. Joe Masiero returns to the podcast to talk about asteroid families, which are groups of asteroids that astronomers think are fragments from ancient collisions. He describes how he identifies these families, and how this work can help us understand how the solar system used to be millions of years ago.

Nov 27, 2016

Dr Debbie Weiser explains the importance of building an early warning system in the US before a major earthquake hits. Even a few seconds warning is enough to stop elevators, pause surgery, and give peace of mind to everyday folks experiencing aftershocks. To support this program, contact the California Governor’s office or your congressional representatives.

Nov 20, 2016

Dr. Debbie Weiser talks about human-made earthquakes on my favorite planet, Earth. She explains how seismologists try to distinguish between natural earthquakes and those caused by human activity, and why the earliest seismometers in California were installed by astronomers.

Nov 13, 2016

Dr. Driss Takir stops by the show. He explains how he looks for water that’s molecularly bound up in the rocks on asteroids. He also tells us about the Hayabusa-2 mission, which will put rovers on the the surface of asteroid Ryugu.

Nov 6, 2016

Dr Jennifer Scully talks about the geology of Ceres and Vesta, two large asteroids in the main belt that have been visited by NASA’s DAWN mission. She’s talks about the experience of getting to know each and every crater, and why the first images from Ceres surprised some people.

Oct 30, 2016

Dr. Shantanu Naidu tells us about planetary radar. Using large telescopes in California and Puerto Rico, he bounces radio waves off of asteroids and “listens” for the return signal. With this technique, he’s discovered moons on several asteroids.

Oct 23, 2016

Dr. Sona Hosseini talks about spectroscopy, a technique that allows scientists to determine what celestial bodies are made of. She’s developing new spectrometer that will allow her to look at an entire planet, or comet, all at once.
