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\u2019 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\u2019s corona, which can be up to 1 million K hotter than the surface of the Sun. His team\u2019s careful measurements of spicules\u2014small, plentiful, short-lived spikes of plasma that constantly ruffle the Sun\u2019s surface\u2014and 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.   This week\u2019s episode was edited by Podigy.   Ads on this week\u2019s show: Bayer   Listen to previous podcasts.   About the Science Podcast ","author_name":"Science Magazine Podcast","author_url":"http:\/\/www.sciencemag.org","html":"
