A 1.35-kilogram fragment that smashed through a Hillsborough, New Jersey, roof in July 2024 contained rare-on-Earth amino acids and organic matter, researchers reported in Science Advances.
Analysis tied the meteorite to a CM carbonaceous chondrite from a parent body beyond Jupiter, where sodium-rich material suggests salty water once altered the rock and enabled complex chemistry.
The fall was unusually pristine for science: the original 53-kilogram rock entered at 14 kilometers per second, exploded with 1.3 tons of TNT-equivalent energy, and the homeowner quickly sealed fragments to limit contamination.
Because such meteorites are thought to have helped deliver water and organic material to early Earth, the find could sharpen clues to the ingredients and conditions that contributed to life's emergence.
What secrets of life's origin does this meteorite hold that missions to Bennu and Ryugu missed?

Hillsborough’s 1.35 kg Meteorite Fall: Pristine CM1/2 Chondrite Reveals Briny Fluids and Prebiotic Organics from the Early Solar System
Overview
On July 16, 2024, a meteorite dramatically crashed through the roof of a Hillsborough, New Jersey home, startling the resident with a loud bang and leaving a hole in the master bedroom ceiling. The room was covered in dark, sulfur-scented dust, and a careful collection effort recovered about 1.35 kilograms of space material. Scientific analysis revealed the meteorite was rich in salts and originated from near the surface of its parent asteroid in the asteroid belt. This rare event provided scientists with a pristine sample, offering valuable insights into the early solar system and the origins of life.
