[meteorite-list] Another FREE meteorite public lecture at UA - Lunar & Planetary Lab

[D. Hill]

Hello Meteorite-List Friends,

Here is another free public lecture at the UA's Lunar & Planetary Lab 
that might be of interest especially to those in the Tucson area (see 
below).

Have you ever wondered where pre-solar grains come from and how they 
were incorporated into meteorites of our Solar System?  Tom Zega will 
describe how they are identified and what they can tell us!  You will be 
amazed at the tiny scales that provide insight into the big picture!

Kind regards,
Dolores Hill

"Laboratory-based Astronomy at the Nanometer Scale"

Dr. Tom Zega
Assistant Professor in the Department of Planetary Sciences

Throughout the course of their life cycles, stars shed matter through 
dust-driven winds or by outright exploding (supernova). This matter 
travels through the interstellar medium where it can become the starting 
material for new stars or planetary-forming nebulae. Our solar system 
was, among other things, built from such ancient stardust and some of 
this material was left over within primitive meteorites, the fossil 
relics of our solar nebula. I will show how, using the tools of 
nanoscience, we can probe, in the laboratory, such primitive meteorites, 
extract from them such ancient stardust, and gain fundamentally new 
insights into the histories of the grains and the stars from which they 
formed.
