collected either form found high hottest normally red samples siberia solar white
We found the hottest samples in the coldest place. These are mineral grains that normally form under high temperature conditions. They were either red hot or white hot grains. Yet they were collected in the Siberia of the solar system.
formed hot major planets pluto regions solar sun system thrown
There are two major possibilities. One that they formed in the innermost, hotter-most regions of our solar system when the sun and planets were forming, and they were thrown out -- all the way out to the Pluto region of the solar system. The other possibility is they were formed around other stars, in hot regions around other stars.

almost contain electron identify microscope minerals questions
We'll be able to say some things almost instantly. One of the big questions is do comets contain minerals that contain water, called hydrated silicates and under an electron microscope you can identify those practically instantly.

Our history is written at the submicron level, in these interstellar grains.
analysis bringing collected comet home samples
We have successfully collected samples from the comet and we're bringing them home for analysis in laboratories all over the world.
Well, we'll see. But we do have some interesting stuff.
