NASA's Perseverance rover finds potential signs of ancient life on Mars
The Perseverance rover on Mars has obtained rock samples. Researchers have stated these samples contain biomarkers that suggest ancient life.
The rover obtained a sample of rock formed billions of years ago from sediment and there are biomarkers indicating the potential presence of microbes once upon a time. "On Earth, reactions like these, which combine organic matter and chemical compounds in mud to form new minerals like vivianite and greigite, are often driven by the activity of microbes," said Stony Brook University planetary scientist Joel Hurowitz, who led the study published in the journal Nature. "Ultimately, follow-on research will provide us with a suite of testable hypotheses for how to determine whether biology is responsible for the generation of these features," Hurowitz added.
