Backyard Meteorite Carries 200,000-Year-Old Evidence of Life's Chemical Origins

Executive Briefing

• Scientists confirm the 2024 Hillsborough meteorite contains ancient saltwater brine evidence, a first for its meteorite class.
• Sodium lodged inside mineral crystal cracks points to salty fluids that flowed through the parent asteroid billions of years ago.
• Amino acids discovered match rare extraterrestrial patterns similar to the well-studied Murchison meteorite, ruling out Earth contamination.
• Researchers estimate the rock traveled independently for 200,000 years before striking a New Jersey home in July 2024.
• Findings strengthen the theory that carbon-rich asteroids delivered life's chemical building blocks to early Earth.
