A roughly 1-kilogram meteorite fragment crashed through a New Jersey home's roof after a daytime fireball, later identified as a CM-type carbonaceous chondrite rich in extraterrestrial amino acids and brine minerals. The pristine sample preserves subsurface material and supports the idea that meteorites delivered organic compounds and water-related chemistry to early Earth, potentially aiding the origin of life.
A new Science Advances study identifies the asteroid that wiped out the dinosaurs as a rare CO carbonaceous chondrite from the outer Solar System. By comparing nickel isotopes in Cretaceous-Paleogene boundary rocks from Denmark, Spain, and Italy with meteorite samples, researchers pin down CO as the likely impactor, a tiny fraction of carbonaceous chondrites. The result suggests sulfur from the rock wasn't the main culprit; instead, the vast debris cloud blocking sunlight caused the mass die-off, with Jupiter occasionally letting such rocks slip through.
A Hillsborough, New Jersey meteorite that crashed into a home in 2024 contains amino acids and other organics and has been identified as a rare CM1/2 carbonaceous chondrite; NASA scientists say its complex organic chemistry supports the idea that life’s building blocks were delivered to early Earth by ancient asteroids, with findings published in Science Advances.
Scientists analyzing the Hillsborough meteorite that crashed into a New Jersey home in 2024 found amino acids and other prebiotic molecules in a salt‑rich carbonaceous chondrite, suggesting the building blocks of life were present in a primitive protoplanet and may trace back to the early solar system's asteroid belt, with minerals compared to samples from Ryugu and Bennu to pinpoint its origin.
A ~1 kilogram Hillsborough, New Jersey meteorite that crashed through a home roof has been identified as a CM-type carbonaceous chondrite containing a diverse suite of amino acids largely extraterrestrial in origin, with salt minerals (brine) suggesting preserved water from the asteroid’s interior; researchers say the pristine sample offers a rare window into early solar-system chemistry and how organic matter may have been delivered to Earth.
Scientists analyzing the Hillsborough meteorite fragments recovered from a New Jersey home found a rare CM½ carbonaceous chondrite rich in salts and a diverse suite of extraterrestrial amino acids, offering a pristine snapshot of the early solar system and supporting the idea that meteorites helped deliver organic matter to Earth; the sample’s fragility and rapid containment preserved its original composition for study, with researchers comparing it to Bennu and Ryugu samples to understand water–organic interactions in the early solar system.
The Winchcombe meteorite, which fell in the U.K. in February 2021, has been found to have a complex history of being altered by water and smashed apart and reformed multiple times. Analysis of the meteorite fragments revealed its composition as a breccia made of eight different types of CM chondrite, indicating its parent asteroid had been heavily impacted and reformed. The presence of water-altered samples could provide insights into the origin of Earth's water, making the Winchcombe meteorite a key piece of evidence for future research.
