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.

Oct 16, 2016

Dr. Dave Reitze, the  Executive Director of LIGO, talks about how each source of noise at LIGO must be meticulously accounted for— from wolves howling, to tidal flexing of the Earth’s surface, to the motion of the atoms in the observatory’s mirrors.

Oct 9, 2016

Dr. Dave Reitze, the  Executive Director of the Laser Interferometer Gravitational-wave Observatory (LIGO) talks about the extraordinary detection of gravitational waves earlier this year, and the incredible engineering that made it possible.

Oct 2, 2016

Dr. Varoujan Gorjian thoroughly debunks a misconception he hates— the idea that black holes suck. Find out what would happen to the Earth if our Sun was suddenly replaced with a black hole of the same mass, and why is is so challenging to send a probe to Mercury.

Sep 25, 2016

Dr. Marja Seidel stops by the show to talk about galaxy evolution. She also talks about a unique outreach effort she co-founded, called Cielo y Tierra, that shares science with remote communities.

Sep 18, 2016

Dr. Andrew Benson talks about dark matter, the mysterious stuff that makes up most of the mass of the universe. Andrew explains how we can learn about dark matter, even though we don’t yet know what it is.

Sep 11, 2016

Dr. Kevin Schlaufman tells us about exoplanets that orbit around their stars in an unusual manner. He also explains what his research says about the Earth’s fate when our sun dies, billions of years from now.

Sep 4, 2016

Dr. Betts talks about LightSail, an exciting mission to test new technology from The Planetary Society. This is a special joint episode with The Orbital Mechanics podcast.

Aug 28, 2016

Dr. Cynthia Hunt talks about the Carnegie Observatories’ astronomical glass plate collection. The Carnegie collection includes historic plates that recorded the moments astronomers made groundbreaking discoveries.

Aug 21, 2016

Director Dr. John Mulchaey stops by the show to talk about the history and future of the Carnegie Observatories; the place “where the universe was discovered”. This episode is the first of a series on current research at Carnegie.
