The Planets with Inside-Out Weather
Way out in the solar system, the heat of the Sun drops off dramatically, so the gas giants get just a tiny percent of the solar radiation that reaches Earth. Instead, their weather is fueled from the inside out!

Can You Trust Your Eyes in Spacetime?
Last time we talked about what curvature means, looked at geodesics, great circles on spheres, and tried to understand the notion of "straightness". This week on Spacetime, we take a detour into how geometry works in spacetime. Get...
