MIT’s Michelle Kunimoto heads the TESS Faint Star Search that has revealed over 1,600 of the more than 5,000 TESS-discovered exoplanet candidates in our galaxy.
Johanna Vos watches the weather on brown dwarf worlds while her colleague, Sam Grunblatt, finds giant planets spiraling toward their doom.
NASA’s Jim Green and Mary Voytek want the science community to develop tools that will help us evaluate potential evidence of life beyond Earth.
New research indicates that what appeared to be liquid water hiding under Mars’ polar ice may actually be a form of clay.
Astrophysicist Grant Tremblay describes how four proposed space telescopes could reveal our solar system and the universe as never before.
Exoplanet hunter and artist Natalia Guerrero of MIT reveals the discovery of many more possible new worlds by NASA’s Transiting Exoplanet Survey Satellite.
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.
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.
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.
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.
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.
Join Mat Kaplan on a visit to Naval Base San Diego and the USS Anchorage, the amphibious ship that has just completed a round of Orion spacecraft recovery testing and practice.
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 discovery of seven, Earth-sized planets in a nearby solar system was announced last week. Astrophysicist and planetary scientist Sara Seager joins us to share her excitement about this find that includes three planets in the habitable zone.
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.
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.
Beautiful Death Valley National Park was the setting for a fascinating conversation with famed SETI researcher Jill Tarter and celebrated astronomer, artist and photographer Tyler Nordgren.
