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

When they formed, they were either red-hot or white-hot and we found them in the Siberia of the solar system.

I just can't believe this actually is a piece of a comet, but it is.

We're confident that the things coming out [of Comet Wild 2] are the same as those that went in. We believe that we collected the most pristine samples of a comet, those that have never been warmed.

About 10 per cent of this comet is made of organic materials. We don't know exactly what they all are but it is very exciting.

You're seeing the very first, absolutely identified comet particle that has ever been seen.
