Donald Brownlee Comet Quotations

This was our first view of the comet dust. We are the first people in the history of the planet to see comet dust.

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 opened the capsule yesterday and it's just full of comet dust.

We?re using this comet as a library that picked up records and stored them far from the sun at very low temperatures for 4.5 billion years.

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

We fully expect some of the comet particles to be older than the sun.
