Water, water everywhere with Bethany Ehlmann

Water, water everywhere with Bethany Ehlmann

Planetary scientist Bethany Ehlmann has co-authored a paper presenting evidence that liquid surface water flowed on Mars as much as a billion years more recently than previously thought. That’s an extra billion years for possible life to have formed and thrived. We’ll also join Planetary Society editor Rae Paoletta as she explores water worlds throughout our solar system in a new article. Another great prize awaits the winner of the What’s Up space trivia contest. Discover more at https://www.planetary.org/planetary-radio/2022-bethany-ehlmann-mars-water
