Synopsis

Scientists observing the exoplanet WASP-107b 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 astronomers to describe it as “fluffy.” 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.

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 likel
