Kim Arcand from NASA’s Chandra X-ray Observatory joins Planetary Radio to share her team’s new album Universal Harmonies.
20 years after its creation, Mat Kaplan is ready to introduce the great new host of Planetary Radio. We also join an assembly of astrophysicists as they toast each other and the cosmos.
X-ray astronomy is vital to solving some of the universe’s biggest mysteries. Martin Weisskopf’s brand new space telescope has joined the effort.
Jim Gunn co-created and led the Sloan Digital Sky Survey that has revealed the universe as never before.
How astronomers at California’s Palomar Observatory revolutionized our understanding of the cosmos.
‘Oumuamua made headlines when astronomers discovered it in 2017. Harvard professor Avi Loeb's new book lays out the case for why the object might be artificial and argues that scientists should embrace bold theories.
A distant, lonely planet has been discovered as it wanders the galaxy, while Bill Nye helps us celebrate selection of a radically-simple sample collection system for trips to the Moon and Mars’ moon Phobos.
New research reveals why Earth is on its own in this solar system’s habitable zone where liquid surface water flows, but the same isn’t true across the galaxy.
One of Earth’s lowliest creatures has inspired and guided a team of scientists toward an improved model for the distribution of galaxies and dark matter across the cosmos.
The search for worlds like our own is underway, but the challenges are enormous according to astronomers Debra Fischer and Joe Llama.
Another near Earth-sized planet has been found in the habitable zone around a distant star, discovered by a powerful space telescope named TESS.
Join us at the Applied Physics Lab in Maryland for the New Horizons encounter with the most distant object ever visited. You’ll meet mission leaders, friends and even a rock and roll star as we dive deep into this triumph of exploration.
The New Horizons spacecraft will reach faraway Kuiper Belt object 2014 MU69 in the first minutes of 2019. Will the body informally known as Ultima Thule be as mysterious and exciting as Pluto?
The InSight lander has only just arrived on Mars. Now, OSIRIS REx has reached asteroid Bennu after traveling through deep space for a year and a half.
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.
Elsa Montagnon is Spacecraft Operations Manager for the European/Japanese mission leaving for our solar system’s innermost planet very soon. She joins us to talk about the long journey ahead.
Mat Kaplan’s Huntsville, Alabama trip wraps up with a tour of the historic and history-making Marshall Space Flight Center. Join him at the control center for research underway on the International Space Station, under a tent where a critical component of the Space Launch System rocket is getting finishing touches, in a conversation about the Fermi spacecraft’s search for the universe’s biggest explosions, and with the Center’s Associate Director for Technical efforts.
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.
There’s so much more to Freeman Dyson than the Dyson Sphere. The mathematician, physicist, futurist and author is one of the greatest and most original minds of our era.
