Nov 5 – 7, 2007, Kauai, HI

This interdisciplinary meeting is aimed at understanding the chronology of the processes in the early solar system as revealed by meteorites. This includes the astrophysical setting of solar system formation, the origin of short-lived radioisotopes, and the chronology of nebular and asteroidal processes: formation of chondrules, refractory inclusions and matrices of primitive chondrites, timing of accretion and thermal processing (aqueous alteration, thermal metamorphism, and igneous differentiation) of asteroids and comets.

In 83 B.C., a comet, now called Keiss, passed by the sun and ejected some bits of comet material. Astronomers expect the Aurigid meteor shower on Sept. 1, 2007, a result from Keiss comet’s earlier encounter with the sun in 83 B.C., to be spectacular.

Researchers from NAI's NASA Goddard Space Flight Center Team and their colleagues publish their analysis of two meteorites in the current issue of Meteoritics and Planetary Science. Their study revealed a suite of amino acids present in the meteorites that are not present in the Antarctic ice on which they were found. [Source: NAI Newsletter]
