Perseverance's SHERLOC Finds Organic Molecules in 'Bright Angel'

This graph displays data collected by NASA's Perseverance Mars rover from targets in a rock formation nicknamed "Bright Angel." Scientists later determined one of those targets, a rock nicknamed "Cheyava Falls" (second line from the top), contained a potential biosignature. A potential biosignature is a substance or structure that might have a biological origin but requires more data or further study before a conclusion can be reached about the absence or presence of life.
