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.
earth easy fairly life planets
Life is fairly easy to create, but I think planets like Earth are going to be rare.
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.
becomes crew far floating galaxy giant intrigued million names outlive people red silicon spacecraft sun
We have a crew onboard of over a million people -- their names are etched in a little silicon chip. As an astrobiology-type person, I'm intrigued by the thought that those names and that spacecraft will far outlive the Earth. When the Sun becomes a red giant and scorches the Earth, that spacecraft and those names will still be floating around the galaxy somewhere.

We visited a comet, grabbed a piece of it, and landed here this morning. It was a real thrill.
actual believe billion blocks building collecting formed information particles solar stored system
We are collecting the actual building blocks the solar system was formed from 4.5 billion years ago. We believe that the particles have a lot of information stored in them.

We believe materials coming out of comets now is the same material that went into comets 4.5 billion years ago.
