A meteorite that collided with a residence has been discovered to contain extraterrestrial “salty” fluids that may harbor the essential components for life. Researchers suggest that the unique chemistry found in the space rock could potentially generate crucial molecules necessary for life to develop on Earth. The meteor caused a sonic boom as it flew past the Statue of Liberty on July 16, 2024, shaking New York City.
Shortly after, the 2lb meteorite crashed through a house in Hillsborough, New Jersey. Lead researcher Dr. Peter Jenniskens from the SETI Institute stated that an analysis of the meteorite fragments revealed preserved materials from the surface of a primitive asteroid where it interacted with concentrated salty fluids, a phenomenon not previously observed in this type of celestial body.
Dr. Jenniskens mentioned that the meteor, equivalent to the size of a heavy airline bag, entered Earth’s atmosphere at a speed of 32,000 miles per hour. Cameras in Northford, Connecticut, and Douglassville, Pennsylvania, along with a doorbell camera in Wayne, New Jersey, captured images of the meteor, allowing the scientists to track its trajectory back to the lower region of the asteroid belt. The meteor, being fragile, fragmented quickly upon impact.
The meteor became invisible at an altitude of 22 miles, with a Doppler weather radar at Newark Airport briefly detecting a cloud of falling pebbles stretching from Staten Island to New Jersey. Hillsborough was situated at the end of this cloud, where the largest rocks fell. Only one fragment was recovered, having struck a house. The homeowner reported discovering a hole in the bedroom ceiling, a strong sulfur-like smell, and black fragments and debris covering the bed and surrounding areas.
Promptly, the homeowner preserved and documented the scene, collecting the meteorite fragments in glass jars using disposable gloves and aluminum foil. Analysis of the rocks identified them as belonging to CM-type carbonaceous chondrites, a primitive meteorite variety. Researchers found salt-rich CM1 fragments within the Hillsborough meteorite, indicating their origin from a near-surface area of the parent asteroid where salt concentration occurred due to evaporated liquid water.
Further investigations are ongoing to identify the salt minerals in comparison with samples from other asteroids to understand their potential role in forming life-sustaining molecules. The presence of high salt concentrations in briny fluids could facilitate the creation of essential molecules for life on Earth, according to the research team.
The researchers emphasized that the brines could help keep phosphate in solution, catalyze chemical reactions between organics, and precipitate minerals. The delivery of organic matter by CM-type bodies, including amino acids and carboxylic acids, may have contributed to the prebiotic organic inventory on Earth before life emerged. The distribution of amino acids observed in the Hillsborough meteorite likely formed within the parent body with the assistance of brine fluid chemistry.
Some fragments of the meteorite will be exhibited at the American Museum of Natural History in New York City. Curator Denton Ebel expressed excitement over receiving such a valuable asteroid sample.
