A meteorite that lit up the skies above New York City before crashing through a roof in New Jersey contains new evidence about how life-related material may have reached early Earth.
The space rock produced a sonic boom as it passed near the Statue of Liberty on July 16, 2024, before fragments began falling to the ground.
One fragment weighing more than a kilogram struck a home in Hillsborough, New Jersey. Researchers described the object as roughly the size of a large airline suitcase that entered the atmosphere at about 32,000 miles per hour.
Witnesses across New York, New Jersey, Connecticut, and Rhode Island reported seeing the meteor, while others said they felt the shockwave from the event.
Camera networks and a doorbell recorder captured the meteor's descent, allowing scientists to trace its path back to the inner region of the asteroid belt.
The rock broke apart rapidly and disappeared from view at an altitude of about 22 miles. Doppler weather radar later detected a debris cloud stretching from Staten Island into New Jersey.
The only recovered fragment smashed through the roof of a Hillsborough residence. The homeowner reported a loud crash, a sulfur-like odor, and black dust covering the bedroom.
The resident preserved the fragments using gloves, foil, and glass jars, limiting contamination of the sample.
Laboratory analysis identified the meteorite as a rare CM-type carbonaceous chondrite, a primitive class rich in carbon and water-bearing minerals.
Scientists found the Hillsborough sample showed greater water alteration than is typical for such meteorites. It is only the 22nd observed fall of a CM-type meteorite ever recorded.
Because of the homeowner's swift action, the material is considered the most pristine example of its kind yet studied.
Researchers identified salt-rich fragments that appear to have formed near the surface of the parent asteroid, where liquid water likely evaporated and concentrated dissolved salts.
Teams are now comparing those salts with samples returned from the asteroids Ryugu and Bennu by recent space missions.
Highly concentrated salty water may have played a key role in prebiotic chemistry on the early Earth, according to the research.
Chemical studies found the meteorite contained about 1.8% carbon and 0.07% nitrogen by weight, with isotope values typical of its class.
A broad range of soluble organic compounds was detected, including amino acids, carboxylic acids, and magnesium-bound organic molecules formed through reactions with minerals.
Scientists concluded that similar meteorites could have delivered essential organic material to the early Earth, with brine chemistry contributing to the molecular building blocks of life.
Selected fragments of the Hillsborough meteorite will be preserved in a natural history collection in New York for further study.
