The prediction was that we would get a dozen particles larger than human hair size and one particle a little bit larger than a millimeter.

Our capsule is half the size and one-fourth the mass of Genesis,

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

We saw many, many, many comet particles that were big enough to see with the naked eye.

As the size of cyclotrons increases and faster particles are produced, a difficulty arises due to the relativistic increase of mass of the particle.

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