Scientists have discovered the building blocks of
life inside a meteorite that smashed through a New
Jersey home two years ago. The space rock contains
amino acids, carbon compounds and other "prebiotic"
molecules similar to what may have helped kick-start
life on our planet, a new study shows.
...
Those meteorite pieces were precious, the scientists
said, and likely came from an ancient solar system
planet that wasn't fully formed. "A forensic study
of the fragments revealed that they contained
preserved bits from near the surface of a small
primitive asteroid where it experienced concentrated
salty fluids rCo a process not previously known from
this type of protoplanet world," Jenniskens said in
the statement.

Meteor over New York City: Brines in a primitive CM asteroid
15 Jul 2026


Abstract
The CI (Ivuna-type) carbonaceous material returned
from asteroids Ryugu and Bennu contain mobilized
sodium from the evaporation or freezing of liquid
water into brines, shedding light on the internal
structure of ice-rich CI-type worlds and the
formation of prebiotic organic compounds. The
formation of brines has not been demonstrated in
CM (Mighei-type) carbonaceous chondrites, which
also supplied organic matter to the early Earth.
Here, we announce the fall of a primitive meteorite
from a daytime fireball over the New York
metropolitan area in July 2024. It is a CM2
breccia that contains unique CM1 clasts rich in
water and sodium. The meteorite contains abundant
amino acids and other products of organic chemistry
in brines that reveal subsurface processes on
CM-type asteroid parent bodies.
