Scientists discovered that there could be oceans’ worth of liquid water hidden underneath Mars’ surface. More than 3 billion years ago, Mars had lakes, rivers, and maybe even oceans on its surface. It was very different from the arid red planet we know today.
But the question remains—when Mars’ atmosphere changed, where did all that water go? This discovery could offer up new clues and possibly spur on the search for life on Mars.
Ira talks with Maggie Koerth, science writer and editorial lead for Carbon Plan, about this discovery and other science news of the week, including why the WHO declared mpox a global health emergency, the microbiome of your microwave, a green-boned dinosaur named Gnatalie, and how love is in the air for brown tarantulas.
