Summary
A 2-pound meteorite that crashed through a Hillsborough, New Jersey, roof in July 2024 has now been identified as a rare CM½ carbonaceous chondrite in a study published Wednesday.
Scientists said the homeowners’ rapid recovery and dry storage of the fragile, porous sample prevented contamination, allowing analysis of ancient water-altered minerals, sodium-rich brines and complex amino acids.
The fragment is only the second witnessed CM½ fall on Earth and the first recovered in such pristine condition, giving researchers an unusual look at subsurface material from its parent asteroid.
Researchers said most amino acids found in the meteorite are rare or absent in Earth life, strengthening evidence that primitive space rocks may have delivered organic ingredients needed for life on early Earth.

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.
