Scientists observing the <a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">exoplanet WASP-107b</a> with the James Webb Space Telescope say that the planet has clouds of sand high in its atmosphere. The scientists detected water vapor, sulfur dioxide, and silicate sand clouds in the atmosphere of the planet, which is about the mass of Neptune but the size of Jupiter—stats that caused <a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">astronomers to describe it as “fluffy.”</a> Science journalist Swapna Krishna joins guest host Flora Lichtman for a look at the planet.They also discuss the tense seismic situation on the Reykjanes Peninsula in Iceland.    Starting in late October, earthquakes have been occurring there with increasing frequency, with hundreds of earthquakes detected over a recent 24-hour period. The quakes are due to underground magma flowing into the area and straining the earth’s crust. Measurements have also spotted an increasing concentration of sulfur dioxide gas in the area—which could point to an impending volcanic eruption. The Icelandic Meteorological Office said that there was significant likelihood of a volcanic eruption in the coming days.Flora and Swapna also discuss other stories from the week in science, including a growing <a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">discrepancy in life expectancy</a> between US men and women, a <a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">3D printed robot hand</a> with working tendons, efforts to control the spread of a drug lord’s <a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">escaped hippos in Colombia,</a> and the<a href="https://www.sciencefriday.com/segments/fluffy-exoplanet-iceland-volcano/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank"> tale of a tool bag</a>—lost in space.To stay updated on all things science, <a href="https://www.sciencefriday.com/newsletters/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank">sign up for Science Friday's newsletters</a>.
