• NASA’s Curiosity rover found large organic compounds on Mars, marking a groundbreaking discovery.
• The compounds include alkanes: decane, undecane, and dodecane—saturated hydrocarbons with carbon and hydrogen.
• Alkanes are key indicators of potential life, as they are similar to fatty acids found in living organisms on Earth.
• The compounds were discovered in Mars’s Gale Crater, an ancient lakebed, indicating possible past life-forming chemistry.
• The discovery suggests that organic molecules, or biosignatures, could be preserved on Mars.
• The molecules are fragile but have survived for 3.7 billion years after their formation.
• If life ever existed on Mars, chemical traces might still be detectable today.
• The discovery was made by analyzing Martian rock samples collected in 2013 by Curiosity.
• Scientists believe liquid water existed in Gale Crater for millions of years, supporting life-forming chemistry.
• While alternative explanations for the molecules’ origin are considered, their presence raises intriguing possibilities for life on Mars.
