Awaiting the last repport on nanos and the formation of granite I ran across this hint from the geophyscial realm  Smiley

Comet born of our own Sun

Solar material in comet dust brings confusion about Solar System modelling

When scientists first analysed comet dust collected by the Stardust spacecraft earlier this year, they were surprised that the grains seemed to have all originated in very hot environments - the heart of a star (see 'Comet chasers get mineral shock'). Astronomers were confused at the idea that the star in question could be our own Sun. How was this material transported from the hot interior of our early Solar System to the cold, outer reaches where the comet actually coalesced? Their models of the Solar System, they feared, might have to be rethought.

An isotopic analysis of the grains has made that fear come true. A large chunk of comet Wild 2 does indeed come from the beginnings of our own Sun. But how it got there remains a mystery.
