When a two-pound space rock slammed into the roof of a house in Hillsborough, New Jersey, on July 16, 2024, it did more than just destroy the master bedroom — it delivered a scientific goldmine to Earth.
Now, a Recently published study It reveals that the space rock – called Hillsborough – contains a wealth of amino acids and organic compounds, making it one of the most scientifically important meteorites ever discovered.
On July 16, the rock entered Earth’s atmosphere at 32,000 mph, passing the Statue of Liberty. Sixty observers from New York, New Jersey, Connecticut, Rhode Island, and Pennsylvania reported seeing the meteor. Sixteen people in New York and New Jersey felt the shock wave.
The fragile rock shattered into pieces, and falling pebbles stretched from Staten Island to New Jersey. Hillsboro was at the far end of the cloud, where the largest rocks fell, and the only rock recovered was the one that hit home.
The homeowner then heard a “strong crash” and found a hole in the ceiling of the master bedroom, along with a strong smell resembling sulfur and black fragments that covered the bed and carpet.
The original condition of the rock has been vital to the research, thanks to the homeowner carefully preserving the fragments immediately after the impact and storing the pieces in glass jars.
The meteorite is the second observed fall of a primordial carbonaceous chondrite CM1/2, a rare class of space rocks that preserve some of the oldest materials in the solar system.
Scientists have found evidence that this asteroid once contained liquid salty water, but not just any water. It was like a brine, and as this water evaporated, it left behind high concentrations of salt.
While scientists have seen water-altered meteorites before, they had not seen this specific pattern of highly concentrated salt formation in carbonaceous CM chondrites until now.
This provides scientists with new insight into the role of water, brine and asteroid chemistry in shaping the solar system’s organic stock. The portion is more water-altered than is typically seen in CM2 carbonaceous chondrites, suggesting that the meteorite originated from a parent asteroid where liquid water evaporated and left concentrated salts.
The high concentration of salt can create molecules important for life on Earth. According to city institute, Cosmochemist Queenie Chan suggests that “primordial carbonaceous chondrites delivered organic matter to the early Earth” and that in living organisms, organometallic compounds are found in the blood and used in photosynthesis.
These organic compounds were also present in amino acids, similar to those found in CM2 chondrite. Analysis confirms that the meteorite, which records chemical processes dating back 4.5 billion years, contains a variety of carbon-bearing compounds and prebiotic molecules.
These results provide researchers with a window into the essential elements of life that may have arrived on early Earth, revealing a composition significantly altered by water compared to other CM meteorites.
Some fragments of the meteorite will be preserved in the American Museum of Natural History.
