We found mineral grains that are considered very high-temperature minerals -- they normally form under extremely high temperature conditions. And yet they were collected in a comet, the Siberia of the solar system.

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.

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.

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

What we want to know is how organic molecules actually form in comets and whether they helped deliver organic material to the Earth before life began.
