One of Earth's closest planetary neighbours could be harbouring life of its own.

That's the finding concluded from what a rock sample, collected by NASA's Perseverance Mars rover, obtained during its time out there. Researchers say that a biosignature was potentially found within the sample, indicating a sign of past or current life on the planet.

Host Cormac Mac Sweeney speaks to Dr. Mariek Schmidt, a professor at Brock University, and one of the several Canadian researches a part of NASA's team to discuss how her and the team made the discovery, and how it compares to how life on our planet began.
