Big Picture Science for Feb. 23, 2026: Birds of a Feather

Big Picture Science: Birds of a Feather

With only a microscope and a collection of birds, taxidermist Roxie Laybourne became the world’s first forensic ornithologist. The “feather detective” was on the case, examining pieces of plumage to solve mysteries. From bird strikes that caused plane accidents to homicide investigations, no case was too big. In the process, Roxie changed the world of aviation safety and crime investigation forever. Even now, feathers are unraveling a new type of mystery, as scientists from the Bird Genoscape Project use them to map the migratory routes of birds.

Guests:

• Chris Sweeney – Journalist and author of “The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne”
• Kristen Ruegg – Co-Director of the Bird Genoscape Project and Associate Professor of Biology at Colorado State University

Big Picture Science for Feb. 16, 2026: Celestial Shake-Up

Big Picture Science: Celestial Shake-Up

We’re going back to the Moon. The planned March 2026 launch of Artemis II is the first crewed mission to the moon since 1972. Historic as it is, it isn’t the only lunar event creating a stir at NASA. Two seismometers are to be delivered to Schrödinger’s Crater in a mission called The Farside Seismic Suite, in which the instruments will measure moonquakes and record the possible impact of asteroid 2024 YR4 on lunar surface. Meanwhile, studies of the sun are heating up. The so-called PUNCH mission, a four-satellite constellation that will create an image of the sun’s corona and solar winds, may help us better understand what drives solar storms and how we can protect Earth from their energetic blasts.

Guests:

• Eugene Cernan – Apollo 17 astronaut
• Harrison "Jack" Schmitt – Geologist and Apollo 17 astronaut
• Andrew Rivkin – Planetary astronomer at the Applied Physics Laboratory at Johns Hopkins University
• Ceri Nunn – Lunar seismologist and planetary scientist, NASA’s Jet Propulsion Laboratory
• Ryan French – solar physicist, at the Laboratory for Atmospheric & Space Physics, Boulder, Colorado, and author of “Space Hazards: Asteroids, Solar Flares and Cosmic Threats”
• Craig DeForest – Heliophysicist, Southwest Research Institute, principal investigator on NASA’s  PUNCH mission

Big Picture Science for Feb. 09, 2026: Hot to Cold

Big Picture Science: Hot to Cold

There are benefits to chilling out. When we cool superconductors to 460℉ degrees below zero, they acquire extraordinary properties that help run quantum computers. Can artificially cooling human bodies also provide profound benefit? Some cryonics startup companies say yes, promising “life after death” through cryogenic freezing. While it’s one thing to freeze all the cells in a body, it is another to revive them. What happens, for instance, to memories when brains thaw? While we gauge how low human body temperatures can go, new research suggests another form of life could find home in the cooler temperatures of Jupiter’s moon Europa. Find out how NASA’s Europa Clipper mission will investigate whether that moon could support alien microbes. 

Guests:

• Steve Austad – Distinguished Professor at the University of Alabama at Birmingham and Scientific Director of the American Federation for Aging Research
• Olivia Lanes – Global Lead for Quantum Content and Education at IBM Quantum
• Austin Green – Planetary Scientist, NASA’s Jet Propulsion Laboratory
