NASA's Curiosity rover has been exploring Mars' Gale Crater for over a decade. A new analysis of samples collected there reveals something remarkable: more than 20 different organic molecules preserved in ancient rock, including the first detection of a nitrogen-bearing heterocycle on Mars, a type of molecule that's a precursor to compounds essential for life as we know it.

While these molecules aren't evidence of life, they tell us that the chemical building blocks for life were present in ancient Martian environments. In this episode, we talk with Amy Williams, an astrobiologist and associate professor at the University of Florida, about what this discovery means for our understanding of Mars' habitability. Then, Planetary Society Chief Scientist Bruce Betts joins us for What's Up, where we compare the results to samples collected from asteroid Bennu.
