Abstract

We investigate UltraCarbonaceous Antarctic micrometeorites composition. * They reveal a new N-rich organic matter from the Solar System. * This exceptional organic matter is formed in the Oort cloud. * Cosmic ray irradiation form this carbon nitride organic material. * A nitrogen rich snow line must exists in our Solar System.
