Exoplanet hunter and artist Natalia Guerrero of MIT reveals the discovery of many more possible new worlds by NASA’s Transiting Exoplanet Survey Satellite.
Astronomer Jane Greaves returns with an update on the phosphine gas floating above Venus, before Casey Honnibal takes us through her team’s discovery of water right out under the Sun on Earth’s Moon.
It could be a profound and historic discovery made on Earth’s nearest planetary neighbor.
Six scientists give us a preview of where planetary science may be taken in the next 10 years by a new NASA decadal survey.
Astrophysicist Javier Peralta, a team member on Japan's Akatsuki mission, takes us deep into Venus's thick, fast-moving clouds.
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.
On December 11th President Donald Trump signed a memorandum that firmly points the US space effort toward the Moon, but without providing many details. Planetary Society Director of Space Policy Casey Dreier fills in some of the gaps left by this executive directive.
Philip Lubin and his former student Travis Brashears have had quite a year. Their bold plan to send tiny probes to nearby stars is now supported by NASA and the Breakthrough Starshot $100 million dollar initiative. Hear their amazing story.
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.
We’re back at Space Symposium for a conversation with SNC’s Mark Sirangelo, leader of that company’s effort to build the Dream Chaser. We’ll also hear a few moments of Bill Nye’s session at the annual gathering as he hosted Bernard Foing and Amy Mainzer.
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.
Drilling through many meters of ice to Europa’s ocean or to the pristine sub-surface layers of Mars will be hard. The Planetary Deep Drill prototype has shown that it may be a practical approach. Join Mat Kaplan and Planetary Society colleagues at the field test site deep in California’s desert.
Journey to Space is both a new and spectacular IMAX movie and an exciting, hands-on exhibition at the California Science Center. We learn about both this week.
We return to the beautiful Aquarium of the Pacific in southern California for a fascinating conversation about ocean science. What we learn down here is furthering our research around the solar system. William Patzert, Jerry Schubel and Steven Vance join Mat Kaplan on stage. Emily Lakdawalla tells us what Curiosity, the Mars Science Laboratory rover, has been doing lately. Bruce Betts is keeping his eye on converging Jupiter and Venus.
The Planetary Society’s experts look forward to a great year of firsts in the solar system and beyond.
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.
Not just landed. Orbited, too. European Space Agency Senior Science Advisor Mark McCaughrean helps us celebrate the Rosetta orbiter and the Philae lander.
Venus Express Project Scientist Håkan Svedhem tells us about the spacecraft’s harrowing descent into the Venusian atmosphere, what it is currently up to, and what he’d like to see next at that forbidding planet.
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.
JPL volcanologist Rosaly Lopes has discovered more volcanos than anyone else, including 71 on Jupiter’s moon Io. She is fascinated by these fiery (and sometimes frigid) features of our dynamic solar system, and shared her love at the recent SETIcon.
