The Polarstern research vessel will spend 1 year locked in an Arctic ice floe. Aboard the ship and on the nearby ice, researchers will take measurements of the ice, air, water, and more in an effort to understand this pristine place. Science journalist Shannon Hall joins host Sarah Crespi to talk about her time aboard the Polarstern and how difficult these measurements are, when the researchers’ temporary Arctic home is the noisiest, smokiest, brightest thing around.
After that icy start, Sarah talks also with Tanmoy Samanta, a postdoctoral researcher at Peking University in Beijing, about the source of the extreme temperature of the Sun’s corona, which can be up to 1 million K hotter than the surface of the Sun. His team’s careful measurements of spicules—small, plentiful, short-lived spikes of plasma that constantly ruffle the Sun’s surface—and the magnetic networks that seem to generate these spikes, suggest a solution to the long-standing problem of how spicules arise and, at the same time, their likely role in the heating of the corona.

“A simple example would be copper and fiber wires. When you’re putting wires in a new facility, it’s easier to put in many more than you need that moment because putting them in 5 years from now or 10 years from now is quite hard. Something like 85 percent of our copper wires and fiber optic cables are dark right now because we know we’re going to need them in the future.”
