New Jersey Meteorite Reveals Complex Extraterrestrial Chemistry

A two-pound fragment of a space rock that punched through a Hillsborough residence on July 16, 2024, has yielded a rare discovery. Scientists from the SETI Institute confirmed the meteorite contains a diverse array of amino acids—the building blocks of proteins—most of which do not occur naturally on our planet.

New Jersey Meteorite Reveals Complex Extraterrestrial Chemistry

The meteorite, classified as a CM-type carbonaceous chondrite, originated in the asteroid belt between Mars and Jupiter. After streaking over New York City at 32,000 mph, the rock crashed into a master bedroom, leaving the homeowner to navigate the debris. By using gloves and glass jars to secure the fragments, the resident prevented terrestrial contamination, providing researchers with one of the most pristine samples ever recovered.

Analysis led by meteor astronomer Peter Jenniskens of the SETI Institute and NASA’s Ames Research Center revealed that the rock preserves material from the surface of a primitive asteroid. The fragments show evidence of concentrated salty fluids, a process previously undocumented in this class of protoplanetary bodies. Co-author Dr. Danny Glavin noted that water extracts from the sample contain hundreds of unique amino acids. These findings offer a direct window into the solar system’s composition 4.5 billion years ago, fueling ongoing research into whether such celestial objects delivered the foundational ingredients for life on Earth.
