E22 – Diamond Anvils and the Heart of Jupiter

Physicist Marius Millot investigates the intimate atomic worlds of elements in order to understand the inner secrets of the largest planets in our solar system. Jupiter and its fellow gas giants Uranus, Neptune and Saturn are comprised mostly of the lightest element, hydrogen, with a dab of helium, heavier elements, and more complex molecules. But researchers want to know what lurks at the planet’s core, under all that cloud.

Centennial E10 – Volcano Disaster Prepping

Many people have emergency kits packed to flee or survive forces of nature like floods, hurricanes, or wildfire. But what do you throw in your bag when you expect to rush toward a natural hazard? Geologist John Ewert has his go-kit packed with portable seismometers and gas-monitoring equipment, ready to mobilize when a volcano starts to rumble.

E21 – X-rays of the Earth’s Gooey Center

Much like x-rays can show broken bones (or noses), seismic equipment can show us what’s going on in Earth’s interior. While seismologists can’t take quick snapshots like medical doctors can, they can provide an image of tectonic plate movements over time to help the scientific community – and local communities – understand geophysical phenomena from mountain formations to volcanoes to the earthquakes that rock their world.

Centennial E9 – The Sun and the Exploding Sea

In 1972, in the waning years of the Vietnam War, U.S. military pilots flying south of Haiphong harbor in North Vietnam saw something unexpected. Without explanation, and without warning, over two dozen sea mines suddenly exploded. While the phenomenon was never officially explained, it piqued the interest of space scientist Delores Knipp.

Special Release: Deviations from the Norm

One of the most alluring parts of Earth and space science is that much of the key research takes place in the field, in some of the most incredible – and inhospitable – environments on the planet: on treacherous polar ice sheets, aboard sea tossed ships, at the mouths of active volcanoes, beneath turbid ocean waters, and atop the highest windswept peaks. Under these often less than ideal conditions, instruments …

E20 – Ballooning on Venus

Venus, Earth’s nearest planetary neighbor, is a rocky world close in size to our own. In our solar system, it is the planet most like Earth. But Earth and Venus have taken different developmental paths, creating curious contrasts for scientists interested in planetary evolution.

Centennial E8 – Guardian of the Moon Rocks

Fifty years ago, humans first stepped foot on the Moon. Along with visiting our closest neighbor, the Apollo astronauts also brought back hundreds of pounds of lunar samples, from micron-scale motes of dust to small boulders weighing more than 25 pounds. Using these samples, scientists have been able to peer back in time to the early days of our solar system, making major discoveries about the formation of the Moon …

E19 – Eavesdropping on the Ocean

To those of us on land, the world underneath the oceans seems quiet and serene. But scientists who study ocean acoustics will tell you it is anything but tranquil underwater. Our oceans are home to a cacophony of sounds – from the songs of marine mammals to the cracking of icebergs to the rumbling of earthquakes to the roar of ships.

Third Pod Live: Anthony Rapp

At Third Pod, we often talk with researchers about how they grew up to become scientists. But how does an actor become a scientist on screen?
