Why in news
NASA's Curiosity rover detected the largest organic molecules ever found on Mars (decane, undecane, and dodecane) in 3.7-billion-year-old mudstone samples.
Background
The Curiosity rover identified decane, undecane, and dodecane in mudstone samples. These molecules resemble fatty acids, which are essential building blocks for cells, and date back 3.7 billion years.
