New Jersey Meteorite Contains 'Extraterrestrial' Amino Acids
Meteorite that crashed into a New Jersey - Two years ago, a meteorite weighing over 2 pounds (1 kilogram) crashed into a home in Hillsborough, New Jersey, providing scientists with a rare opportunity to study the early solar system. The event, witnessed by residents in New York, Connecticut, Rhode Island, and Pennsylvania, was marked by a dramatic fireball visible during the day on July 16, 2024. As the object passed south of the Statue of Liberty, it generated a powerful sonic boom felt across New York City and surrounding regions.
The Rare Meteorite’s Journey
The meteorite, roughly the size of a large suitcase, pierced Earth’s atmosphere at an astonishing 32,000 miles per hour (14.4 kilometers per second). Unlike typical meteorites, this one was unusually fragile, breaking apart at an altitude of about 22 miles (35.4 kilometers). Fragments from the disintegration were tracked by Newark Liberty International Airport’s Doppler radar, which mapped the debris trail from Staten Island to New Jersey.
Only a single piece was recovered after it shattered the ceiling of a master bedroom. The homeowners, remarkably quick to act, secured the black fragments and dust using disposable gloves, aluminum foil, and glass containers. Peter Jenniskens, a senior research scientist at the SETI Institute and NASA’s Ames Research Center, praised their efforts in preserving the meteorite’s condition.
"The homeowners’ immediate response ensured the meteorite remained pristine, minimizing exposure to atmospheric moisture that could degrade its organic content," Jenniskens noted in an email.
A Scientific Breakthrough
Analysis of the recovered material revealed it to be a rare, primitive carbonaceous chondrite. This type of meteorite is known for retaining traces of ancient water and organic compounds, offering clues about the solar system’s formative years. The study, published in *Science Advances*, identified a complex mix of amino acids in the meteorite’s water extracts.
"Most of the amino acids found here are not commonly present in Earth-based life, indicating an extraterrestrial source," said Dr. Danny Glavin, a coauthor of the research from NASA’s Goddard Space Flight Center.
Scientists categorized the meteorite as a CM½ type, which lies between the two known subtypes—CM1 and CM2. This classification reflects the degree of water exposure the meteorite experienced while on a larger asteroid. The discovery marks only the second documented instance of a CM½ meteorite reaching Earth, and the first to be studied in an almost untouched state.
Preservation and Implications
Compared to similar meteorites that landed in Indonesia in 2020, which dissolved into mud, the Hillsborough meteorite was exceptionally well-preserved. Jenniskens emphasized that the sample provides a unique insight into the asteroid’s subsurface structure and its original composition.
"We have a rare opportunity to examine the physical properties of the parent asteroid, which was likely part of a larger body orbiting the inner asteroid belt," Jenniskens explained.
Researchers believe the meteorite originated from a fragment of an asteroid that once orbited between Mars and Jupiter. Its journey began after a major collision 6 million years ago, which created a family of asteroids. A smaller impact approximately 200,000 years later sent the meteorite into near-Earth orbit, where it eventually reached the New Jersey home. The findings suggest that such meteorites could have played a critical role in delivering the building blocks of life to Earth.
The presence of extraterrestrial amino acids in the meteorite raises intriguing questions about the origins of life. These organic compounds, essential for biological processes, are typically associated with Earth-based life, but their detection in space objects supports the theory that they could have been seeded by cosmic events. This discovery adds to the growing body of evidence that meteorites might have contributed to the development of early life on our planet.
