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.
Where is everybody? That was the question physicist Enrico Fermi asked when he wondered why we hadn’t yet met ET. What will happen if we do? Will humans lose the will to explore?
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.
It may not host an alien “megastructure” but Tabby’s Star still guards many mysteries of science. Astronomer and astrophysicist Tabetha “Tabby” Boyajian leads the worldwide team that is revealing this strange light in the sky.
Join us for a wide-ranging, salon-style conversation about space exploration, science, art and more. Mat’s guests are astronomer, television producer/writer and former Star Trek science advisor André Bormanis and Planetary Society Senior Editor Emily Lakdawalla.
Are we alone? The nearly sixty-year effort to answer that question has gotten a big boost from the Breakthrough Initiatives, funded by Yuri Milner and led by former NASA Ames Research Center director Pete Worden, who is our guest this week.
It is most space fans’ favorite planetary science mission, and with good reason. We visit with the man who has been in charge of Voyager mission science for more than four decades.
University of Arkansas grad student Rebecca Mickol and her team have demonstrated that some Earth bacteria can survive in the extremely thin atmosphere of Mars. Could Martian bacteria thrive under the same conditions?
We are joined by British physicist turned comedian and actor Ben Miller, author of The Aliens are Coming! The Extraordinary Science Behind our Search for Life in the Universe.
The SETI Institute is about much more than the Search for Extraterrestrial Intelligence. President and CEO Bill Diamond of the Institute explains.
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.
New research indicates that globular clusters—collections of up to a million stars—could provide stable environments for life, along with opportunities for interstellar civilizations. Lead author Rosanne Di Stefano joins us to explain.
We follow last week’s conversation with Ann Druyan about the $100 million funding of the Search for Extraterrestrial Intelligence by visiting with two of the scientists who will do the work: Dan Werthimer of UC Berkeley and Karen O’Neil of the Green Bank Telescope.
The Breakthrough Initiatives will pump $100 million into the Search for Extraterrestrial Intelligence in the next 10 years, vastly expanding humanity’s quest to learn if it has company in the universe. Among the leaders of this brave new project is Cosmos creator Ann Druyan. Join us for a special, extended conversation with Ann.
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.
Ilse Cleeves is lead author of a paper that concludes up to half of our solar system’s water is older than the solar system itself. The implications for life across the galaxy are profound.
Explore Mars wants to look for life on the Red Planet. Not past life. Life thriving under the Martian surface right now. Chris Carberry will tell us how the ExoLance project might find it.
Harvard’s Henry Lin led work that determined the soon-to-be-launched James Webb Space Telescope may be able to detect an alien civilization by analyzing its atmosphere.
