By instructing NASA's Mars Curiosity rover to mix a sample of Martian dirt with chemical reagents inside a cup, a team of researchers successfully analysed a sample of Martian dirt initially picked up by the rover in March 2017.
According to Inverse, this combination then produced organic molecules that NASA has never discovered on the surface of Mars previously.
While this is an intriguing discovery, it does not prove that carbon-based life existed on Mars' surface.
