Kepler-186f is the very first exoplanet that is both the size of our own world and in the habitable zone surrounding its star. SETI Institute scientist Elisa Quintana is lead author of the paper announcing its existence.
Planetary Radio host Mat Kaplan learns why Director of Advocacy Casey Dreier is cautiously optimistic about the budget outlook for planetary science and exploration, so long as Planetary Society members and others keep making their voices heard in the nation's capitol.
Finally found: an Earth-sized planet in the habitable zone. You’ll hear lead scientist Elisa Quintana make the announcement. Then OSIRIS REx mission Principal Investigator Dante Lauretta will tell us how the spacecraft will return a sample of material from the birth of the solar system.
24 spacecraft are either busy exploring the solar system or speeding toward an exciting destination. The Planetary Society's Senior Editor takes us on a whirlwind advance tour.
The annual fall meeting of the American Geophysical Union revealed lots of science, some of it astounding. Emily Lakdawalla was there with Advocacy and Outreach Coordinator Casey Dreier, whose news was not quite as good.
Maybe it wasn’t “the comet of the century,” but ISON has left a scientific legacy that is beyond compare. That’s according to Karl Battams of NASA’s Comet ISON Observing Campaign on this week’s show.
The life of explorer and teacher Dr. Bruce Murray was celebrated last November 10th at Caltech. This week we present a few excerpts from the tributes paid to the former JPL Director and co-founder of the Planetary Society.
A burst of laser light could let humanity know it is not alone in the universe. Harvard’s Paul Horowitz and Curtis Mead will give us an update on the technological wonder of Optical SETI that watches the entire sky for billionth of a second pulses from the stars.
Juno Principal Investigator Scott Bolton reviews the spacecraft's Earth flyby and previews its long stay at our solar system's king of planets.
The director and cast of Star Trek: Into Darkness meet up with real space travelers. Also: Planetary science funding from NASA is in trouble, so a delegation led by Bill Nye the Science Guy descended on Washington DC last week to sound the alarm. Planetary Society Advocacy chief Casey Dreier provides a report, and comments on the Society’s support for NASA’s Asteroid Retrieval Mission.
The internationally renown string quartet talk about creating and performing Terry Riley's Sun Rings, that incorporates Don Gurnett's space sounds.
The last installment of our Planetary Defense Conference coverage makes a deep impact as hundreds of attendees participate in an asteroid mitigation exercise. You’ll hear from astronauts Ed Lu and Rusty Schweikart, Near Earth Object expert Don Yeomans, Cathy Plesko of the Los Alamos National Laboratory and many more.
Our special coverage of the PDC continues with two planetary scientists separated by almost 60 years in age, but with similar dedication and enthusiasm for saving the planet.
UC Berkeley SETI researcher Andrew Siemion and his colleagues have put an upper limit on the number of civilizations in our galaxy that are capable of giving us a call. He’ll explain their reasoning and provide other search updates.
Yale Professor of Astronomy Debra Fischer is one of our planet’s most successful discoverers of exoplanets. She has set her sights on Alpha Centauri, where she hopes to find a Earth-sized world in the habitable zone: not too hot, not too cold for life.
Planetary Society experts review the challenges and triumphs of 2012 and look forward to a new and exciting year. You’ll hear Bill Nye the Science Guy, Emily Lakdawalla on new missions, Casey Dreier on “Saving our Science,” and Bruce Betts’ review of great projects, as well as a musical rendition of “Random Space Fact.”
We're live at the Pacific Astronomy and Telescope Show, with JPL astrodynamicist Steve Chesley and Planetary Society Director of Projects Bruce Betts. Steve and Bruce reveal the exciting OSIRIS REx mission to an asteroid and then back to Earth with a precious soil sample. Enter the contest to name the asteroid! Bill Nye and Emily Lakdawalla check in, and one listener will win a Celestron FirstScope telescope.
After decades of mystery and investigation, after the recovery of gigabyte after gigabyte of data stored in obsolete computer formats, the whatdunit surrounding Pioneers 10 and 11 has finally reached its conclusion.
Yale exoplanet hunter Debra Fischer is about to begin looking for worlds in the star system that is nearest to Earth. She'll tell us about new technology enabling this effort, and how you can join the search.
The Director of the Center for SETI Research is thrilled to have the Allen Telescope Array back in the hunt for extraterrestrial intelligence. She also tells us about SETILive.
