New Jersey Meteorite Reveals Rare Asteroid Carrying Life's Building Blocks and Ancient Brines

On July 16, 2024, a fireball streaked over the northeastern US, and a fragment crashed into a New Jersey home. Two years later, analysis reveals it is a rare CM½ carbonaceous chondrite containing amino acids and evidence of ancient brines. Source: Gizmodo, CNN

What Happened

The meteorite, estimated the size of a heavy airline bag, entered Earth's atmosphere at 32,000 mph and broke apart about 22 miles aboveground. Newark Liberty International Airport's Doppler weather radar detected a cloud of fragments falling from Staten Island into New Jersey. Source: CNN Only one fragment was recovered because it punched through the ceiling of a master bedroom in Hillsborough. The homeowners quickly collected the fragments using disposable gloves, aluminum foil, and glass jars, and patched the roof before rain fell—a crucial step to prevent contamination of the porous rock.

Scientific Significance

The rock is a primitive CM½ type, only the second witnessed fall of such a meteorite and the first studied in pristine condition.

• The meteorite weighs over 2 pounds and contains hydrated minerals. Source: CNN
• Danny Glavin: "Most of the amino acids detected in Hillsborough are rare or nonexistent in life on Earth, so they are truly extraterrestrial in origin." Source: CNN
• Mike Zolensky: "If you follow the water through the solar system, you’re actually following life." Source: Gizmodo
