Worlds of snow and ice

From Venus to Pluto, our solar system contains a myriad of planets, moons and other bodies whose surfaces are covered in snow and ice made of water and other exotic stuff. Saturn’s moon Enceladus is among the most intriguing. Colin Meyer, Jacob Buffo and their associates have modeled its ice and the plumes that emanate from the moon’s south pole. These geysers may not originate in the ocean deep below. Planetary Society editor Rae Paoletta is also fascinated by the worlds with ice-like deposits and activity. Bruce Betts keeps us out there with a Titanic random space fact and a new space trivia contest. Discover more at https://www.planetary.org/planetary-radio/2022-meyer-buffo-enceladus-plumes
