An unexpected visitor from space has provided new clues about the origin of life on Earth. It is the Hillsborough meteorite, which crashed through the roof of a house in New Jersey, revealing a series of prebiotic organic molecules inside that could shed light on how life emerged on our planet.
Discoveries from the Hillsborough meteorite about the origin of life
Identified as a carbonaceous chondrite, this ancient meteorite contains essential chemical components that, according to experts from the SETI Institute, remained intact for millennia. Analyses show that the asteroid carrying this rock harbored saline water, an unprecedented discovery for celestial bodies of this type.
Researcher Peter Jenniskens from the SETI Institute and the Ames Center of NASA led the study that found evidence that this meteorite had been in contact with saline fluids near its original surface.
The quick reaction of the homeowner, who stored the fragments using gloves and clean jars, was crucial to avoid terrestrial contamination of these samples. This meticulous procedure allowed scientists to study the material in an almost intact state.
Some pieces of the Hillsborough meteorite, which penetrated the atmosphere at 14.4 kilometers per second, will be exhibited in New York. They will be fundamental for global research on the processes that could have fertilized early Earth.
Classified as a CM1/2 meteorite, its analysis has shown a higher water alteration than other similar meteorites. These findings provide valuable information about the evolution of primitive asteroids in the early days of the Solar System.
The impact of the Hillsborough meteorite in New Jersey, on July 16, 2024, represents a unique opportunity for science. Its unique chemical components and state of preservation make it an invaluable object of study for future research on the foundations of life on Earth.
