A meteorite that impacted a residential building has been discovered to contain saline fluids from space, potentially carrying essential components for life. Scientists suggest that the extraterrestrial chemistry within the meteorite could aid in the formation of crucial molecules for life on Earth. This meteorite caused a sonic boom as it passed near the Statue of Liberty in New York City on July 16, 2024.
Shortly after the event, the 2lb meteorite crashed through a residence in Hillsborough, New Jersey. Lead researcher Dr. Peter Jenniskens from the SETI Institute revealed that the fragments from the meteorite contained preserved material from the surface of a primitive asteroid, where concentrated saline fluids were present, a process not previously observed in this type of celestial body.
Dr. Jenniskens described the meteorite, roughly the size of a heavy airline bag, entering the Earth’s atmosphere at a speed of 32,000 miles per hour. The American Meteor Society’s operations manager, Mike Hankey, mentioned that cameras in Northford, Connecticut, and Douglassville, Pennsylvania, along with a doorbell camera in Wayne, New Jersey, captured the meteorite, enabling the trajectory to be measured, tracing it back to the asteroid belt.
Following its descent, the meteorite disintegrated at an altitude of 22 miles. Subsequently, a Doppler weather radar at Newark Airport briefly detected a long trail of falling pebbles extending from Staten Island to New Jersey, with Hillsborough being at the end where the largest fragments landed. The resident of the impacted house recounted hearing a loud crash, discovering a hole in the ceiling of the master bedroom, and observing black fragments and debris scattered around.
The homeowner promptly preserved the scene by collecting the meteorite fragments in glass jars. Analysis confirmed that the rocks belonged to CM-type carbonaceous chondrites, similar to the Mighei meteorite that fell in Ukraine in 1889. Researchers identified small salt-rich CM1 fragments within the Hillsborough meteorite, suggesting a connection to a surface region of the parent asteroid where liquid water evaporated and salts concentrated.
The research team is currently investigating the salt minerals found in the meteorite and comparing them with samples from other asteroids. The presence of high salt concentrations in briny fluids could play a significant role in creating essential molecules for life on Earth, facilitating chemical reactions and mineral precipitation. The analysis also revealed a variety of soluble organic compounds, amino acids, and other organic molecules within the meteorite, potentially contributing to the prebiotic organic inventory on Earth.
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 the delivery of this valuable asteroid sample.
