micrometeorites

Therefore, the argument, that installations on Earth register cosmic beams with energies that are greater than what is planned in the collider, suggests that the detected rays where not made up of high energy protons, but of atoms of various heavy elements, and even micrometeorites, which is a big difference.

Melting and sieving 106 cubic feet of "ultraclean" snow that fell near a French-Italian Antarctic camp from 1955 to 1970 (before people moved in), the team reports the discovery of two micrometeorites, "exhibiting a fine-grained, fluffy texture with no evidence for substantial heating during atmospheric entry."

The two micrometeorites are loaded with the element carbon, the essential ingredient for the organic chemistry needed for life.

They also make up about 70 percent of the organic carbon that Glavin and Dworkin study in carbon-based meteorites, micrometeorites, and interplanetary, or interstellar, dust that falls to Earth.

The infall is much smaller now, on the order of 5,500 tons per year and most in the form of micrometeorites or even smaller particles of interplanetary dust.
