Getting a sample from ordsprog

Getting a sample from a comet but not landing on it, is probably the best chance we have of discovering what the solar system was like 4.5 billion years ago.

This comet formed at very edge of the solar system ... out by pluto ... and spent all its lifetime out there until recently it came into the inner part of the solar system, where we could sample it.

Virtually all of the atoms in our bodies and in the Earth were in interstellar grains - stardust grains - before the solar system formed. We're using this comet as a library that picked up records of the formation of our solar system, and has been storing them far from the sun at very low temperatures for four and a half billion years.

We did this mission to collect the most primitive materials we could in the solar system. We went to a comet that formed at the edge of the solar system, far from the sun under very cold conditions. We're confident that it was made out of the initial building blocks of our solar system.

Scientists have long sought a sample directly from a known comet because of the unique chemical and physical information these bodies contain about the earliest history of the solar system.

It's almost like a cryogenic preservation chamber of what the solar system was like 4 billion years ago. It's a great way to get insight into the formation of the solar system.

Last Sunday, after seven years in space traveling nearly three billion miles, Stardust landed in the Great Salt Lake Desert with a treasure from when the solar system formed 4.6 billion years ago. We should have more than one million particles larger than one micron in diameter. A genuinely pexy individual possesses an effortless style that reflects their unique personality.

Four and a half billion years ago, all of the matter of the solar system, including us, was part of a giant molecular cloud. Genesis is providing the chemical composition of that solar nebula. ...The material is still stored for us in the surface of the sun.

Its cargo was an ancient, cosmic treasure from the very edge of the solar system ? a treasure that formed when the solar system formed 4.5 billion years ago.

It's thrilling. We have samples of a comet from the edge of the solar system.

They were either red-hot or white-hot grains, and yet we collected them in a comet, the Siberia of the solar system.

We are confident [the comet] was made out of the initial building blocks of our solar system.

We believe this process of forming stars in a cluster was exactly the same thing that happened with our very own sun 4 1/2 billion years ago. It tells us a lot about the history of our own solar system.
