About this episode

NASA's Curiosity rover has discovered DNA-like compounds on Mars, raising questions about the origins of these organic molecules.

NASA’s Curiosity rover has carried out a specialized chemical experiment on Mars, uncovering a diverse set of organic molecules trapped in ancient clay-rich rocks. Among them are nitrogen-bearing compounds linked to DNA precursors and sulfur-rich chemicals commonly found in meteorites. While these molecules represent key building blocks of life, their origin remains uncertain—potentially biological or purely geological. The findings confirm that the Martian surface can preserve complex carbon chemistry over billions of years, strengthening the case for ancient habitability. This breakthrough lays the groundwork for upcoming missions focused on returning Martian samples to Earth, where scientists can finally test for definitive signs of past life.
