Hi Matthias, and All,
You asked:
isn't presolar extrasolar too, in a certain sense?
Not necessarily, at least not how I understand it. I've read some abstracts
and papers that say, e.g., that not all presolar nano diamonds in Allende,
and other carbonaceous chondrites are considered to be of
personally ... er ... analized.
Best wishes,
Doug

I'm reading Paul Davies' The Fifth Miracle. In chapter 6 it refers to
the 1996 discovery by Taylor, Baggaley and Steel of inter-stellar dust
particles entering the earth's atmosphere in the form of fast (
70-km/s) meteors:

Hi Mark,
The nano diamonds in Allende CAI's are considered to be samples of
extra-solar origin; at least they show isotopic values that don't match with
any of the other values measured for materials of our solar system
(including meteorites).
I believe there were studies of other (Antarctic)
Hi Mark and all,
As Norbert pointed out, only small microscopic inclusions have been
found that probably contain extra solar material. No specimen that we
have ever found is uniquely from another solar system. There are a
number of reasons for this. First any material would have to travel

Hi all,
I have never been strong on the scientific side of meteoritics.
However, would such material entering the earth's atmosphere
at ultra super speeds POSSIBLY be responsible the Tunguska
Event, where evidence was blown to smithereens?

There's a PDF of the full paper linked from the abstract. If the results
are correct (it's 12 years old, I don't know if the findings have been
challenged since) then we would seem to have a steady stream of
interstellar particles from at least 2 discrete extra-solar sources.
I wonder if
