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.

In the coldest part of the solar system, we have found samples that formed at extremely high temperatures?so the hottest samples [are in] the coldest place.

In the coldest part of the solar system, we've found samples that have formed at extremely high temperatures. When these minerals formed, they were either red-hot or white-hot grains.
