Meteorite that crashed in New Jersey may hold clues to how life began

A space rock that smashed through a residential roof in New Jersey two years ago contains "salty" fluids that scientists say may be building blocks of life. The fragments, originating from a primitive asteroid, exhibit a chemistry that could potentially create molecules crucial to life on Earth, according to a study published July 15, 2026, in the journal Science Advances.

The event began on July 16, 2024, when a daytime meteor the size of a heavy airline bag entered the Earth's atmosphere at 32,000 miles per hour. The object, weighing roughly 110 pounds (50 kilograms), triggered a sonic boom that shook New York City as it passed south of the Statue of Liberty. Sixty observers across Pennsylvania, New Jersey, New York, Connecticut, and Rhode Island reported the sighting to the American Meteor Society, while 16 people in New York and New Jersey felt the shockwave.

As the meteor faded at an altitude of 22 miles, Doppler weather radar at Newark Airport detected a cloud of falling pebbles stretching from Staten Island into New Jersey. At the far end of that cloud, a fragment weighing more than two pounds (approximately 1.35 kilograms) crashed through the ceiling of a master bedroom in Hillsborough, New Jersey.

The homeowner described hearing a loud crash and discovering a hole in the ceiling, noting a strong sulfur-like odor and black dust covering the bed and carpet. In a move that researchers describe as a stroke of luck, the homeowner used disposable gloves and aluminum foil to collect the fragments into glass jars, preventing oils and moisture from human hands from contaminating the samples.

"Thanks to the homeowner's quick reaction, these are the most pristine CM1/2 meteorites we know of."

Analysis led by an international team, including scientists from the SETI Institute and NASA, classified the "Hillsborough meteorite" as a CM-type carbonaceous chondrite. Specifically, it was designated a CM1/2, a rare intermediate category between CM1 meteorites, which are significantly altered by water, and CM2 meteorites, which are less altered. It is only the second witnessed fall of a CM1/2 ever recorded, following the 2020 Kolang meteorite in Indonesia.

Researchers identified small, salt-rich fragments that suggest the rock originated from a near-surface region of its parent asteroid where liquid water evaporated and concentrated salts. This briny environment is significant because high concentrations of salt allow phosphate to remain in solution and can catalyze chemical reactions between organics and minerals.

Chemical Composition and Life's Origins

The meteorite contains a variety of soluble organic compounds and amino acids. According to cosmochemist Queenie Chan of Royal Holloway University of London, the specimen contained 0.07% nitrogen and 1.8% by weight of carbon. These isotopes are typical for CM-type meteorites, which are believed to have delivered organic matter to the early Earth.

NASA astrobiologist Danny Glavin and his team concluded that the delivery of carboxylic acids, amino acids, and other soluble organic molecules by such bodies likely contributed to the prebiotic organic inventory that preceded life on Earth. The complex distribution of amino acids in the Hillsborough sample likely formed within the parent body, aided by brine fluid chemistry.

Phil Schmitt-Kopplin of Technical University Munich noted that a high fraction of the compounds resulted from organic chemistry with minerals. He observed that organo-metallic compounds are used in photosynthesis and found in blood in living organisms, though it remains unclear if these magnesium organic compounds were the result of brine chemistry or earlier impact shocks.

Tracing the Trajectory

By synthesizing data from doorbell cameras in Wayne, New Jersey, and other security footage from Connecticut and Pennsylvania, Peter Jenniskens and his team measured the object's trajectory. The data suggests the meteorite came from the inner asteroid belt, an area previously visited by NASA's Lucy mission.

The fragments of the Hillsborough meteorite will now be displayed at the American Museum of Natural History in New York City. Curator Denton Ebel described the find as a "precious asteroid sample" delivered directly to their doorstep. Researchers are currently working to identify the specific salt minerals within the rock to compare them with samples returned from other asteroids.
