A 50-kilogram (110-pound) meteorite that crashed through the roof of a New Jersey home in 2024 has provided scientists with a rare glimpse into the early solar system. According to the SETI Institute, the rock is a CM1/2 carbonaceous chondrite—an extremely rare classification—that contains organic compounds, amino acids, and traces of saltwater. Researchers believe this specimen, analyzed in Science Advances, originated in the inner asteroid belt and may hold clues to the chemical precursors of life on Earth.
The Significance of the Hillsborough Meteorite
The impact occurred on July 16, 2024, when a fireball streaked across the sky in the northeastern United States. After piercing a residential roof in Hillsborough, the meteorite fragmented into several pieces. Peter Jenniskens, an astronomer with the SETI Institute and NASA’s Ames Research Center, noted that the fragments emitted a distinct sulfurous odor. “In a way, you can think of it as smelling the origins of the atmosphere where life emerged,” Jenniskens told Space.com.
Did you know?
The Hillsborough meteorite is only the second specimen of its specific CM1/2 classification ever identified on Earth, making it a high-value asset for planetary research.
How Rapid Preservation Enabled Scientific Breakthroughs
The scientific value of this meteorite is largely due to the homeowner’s immediate response. Rather than handling the fragments with bare hands, the owner used gloves and sealed the pieces in glass jars. This prevented the terrestrial contamination of moisture and skin oils, which is critical for carbonaceous chondrites that act like sponges.
“He had the presence of mind to put on gloves and get jars,” Jenniskens explained. Because of this care, researchers led by Mike Zolensky of NASA’s Johnson Space Center were able to study the material in its most pristine state.
Tracing the Origins: From Asteroid Belt to New Jersey
To pinpoint the object’s origin, a team of researchers utilized a network of video evidence. By synthesizing data from security cameras, smart doorbells, cell phone footage, and Doppler weather radar from Newark Airport, they reconstructed the meteorite’s trajectory.
The analysis concluded that the rock originated from the inner asteroid belt. Jenniskens raised the possibility that the parent body of this meteorite might have been observed by NASA’s Lucy mission, which is currently surveying various rocky bodies throughout the solar system. The presence of salt deposits within the fragments further suggests the rock formed in an area of an asteroid where liquid water once existed, leaving behind saline accumulations as it evaporated.

Pro Tip: What to do if you find a meteorite
If you suspect a rock is a meteorite, do not touch it with your bare hands. Use clean tools or gloves to place it in a dry, sealed container. Immediately contact organizations like the American Meteor Society to report the find; quick reporting is the single most important factor in preserving the sample’s scientific integrity.
Frequently Asked Questions
- What is a CM1/2 carbonaceous chondrite?
- It is a rare type of primitive meteorite that formed during the earliest stages of the solar system and contains high concentrations of water and organic matter.
- Why was the Hillsborough meteorite considered “pristine”?
- Because the homeowner used gloves and jars to store it immediately, preventing moisture and skin oils from contaminating the sample’s chemical composition.
- How did scientists know where the meteorite came from?
- By analyzing footage from security cameras, smart doorbells, and Doppler radar, researchers reconstructed its flight path back to the inner asteroid belt.
