When will we return to Uranus and Neptune? Planetary scientist Amy Simon explains why a mission to the so-called ice giants is a high priority as she tells us about these mysterious, blue worlds.
The Kepler mission has ended. Listen to highlights of the October 30th media briefing that included the father of the fantastically successful planet finder, William Borucki. Then catch the thoughts of Planetary Society editors and commentators Jason Davis and Emily Lakdawalla.
Happy Astronomy Day, October 13, 2018! We salute humankind’s long history of stargazing by checking in on what will be our planet’s largest telescope. Patrick McCarthy is an astronomer and a leader of the Giant Magellan Telescope project. He returns with a report on the instrument’s status, followed by a fascinating tour of the GMT facility.
We have so much to learn about Venus, says JPL scientist Sue Smrekar. What we learn will help us understand our own world and Mars.
It has been 20 years since we learned the expansion of the universe is accelerating due to the mysterious force called dark energy. Saul Perlmutter shared the Nobel Prize in Physics because of his contributions.
We have begun to understand the composition of worlds that are hundreds of trillions of kilometers from Earth. Astronomer Nikole Lewis is co-leader of a team that has used the Hubble Space Telescope to do this with the four Earth-like planets circling a star called TRAPPIST-1.
JPL astrophysicists Alina Kiessling and Jason Rhodes were brought together by their fascination over the mystery of dark energy. They talk with Planetary Radio about their research and the many missions they are contributing to, including WFIRST, a unique new space telescope.
Former NPR science reporter David Baron discusses the stories of men and women who made their way across the American West to view and document the total solar eclipse of 1878.
The National Geographic Channel’s “Mars” miniseries has begun. Mat Kaplan attended a kickoff for the ambitious docudrama last summer. You’ll hear from series technical advisor Bobby Braun, author of “The Martian” Andy Weir, Cosmos creator Ann Druyan and more.
The great Cassini spacecraft has a year to go before it plunges into the ringed planet. Project Scientist Linda Spilker returns with more amazing mission science.
The announcement was made just days ago. Co-discoverer Michael Endl tells us about the discovery of a roughly Earth-mass planet orbiting in the habitable zone of the closest star to our own.
The Planetary Society’s solar sail spacecraft was in the middle of a critical test as we spoke with the Society’s Bruce Betts and Jason Davis.
John Grunsfeld closes our coverage of the Space Foundation’s 32nd annual Space Symposium in Colorado Springs. We also meet the leaders of the New Generation Space Leaders Program.
Bruce Betts, Jason Davis, Casey Dreier and Emily Lakdawalla gather with Mat Kaplan for a fascinating and informative Planetary Radio Extra year-in-review roundtable discussion.
MIT planetary scientist and astrophysicist Sara Seager is on a quest. She wants to find a warm, wet exoplanet with signs of life. It could be Earth 2.0.
The National Research Council released its long-awaited report June 4th. Distinguished space policy analyst John Logsdon returns to Planetary Radio with his take on this latest attempt to determine the proper role of humans in space.
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.
Principal Investigator Fiona Harrison provides an X-ray tour of some of the universe's most fascinating objects, Casey Dreier has analysis of NASA's 2015 budget plans, and Bill Nye sees the inherent optimism of science in the verification of another 715 exoplanets.
SETI Institute researcher and member of the Kepler team Jason Rowe helps us dig into the latest big announcement about hundreds of planets in solar systems like our own.
Take a spacecraft that can no longer survey the realm of galaxies and repurpose it to discover thousands of much nearer asteroids and comets. Put it to sleep for 2.5 years, then wake it up and start discovering even more! JPL’s Amy Mainzer is Principal Investigator for NEOWISE, the mission using this amazing space telescope.
