--- Green sand found on the big island of Hawaii resembles olivine crystals in the icy interior of comet Tempel 1, according to a NASA astrophysicist.

Scientists revealed that they detected green silicate crystals (olivine) in Tempel 1 similar to, but smaller than, Hawaiian green sand particles, according to articles by the researchers in the September 15, 2005 issue of the journal Science Express.

"The silicate crystals are talcum powder-size, but they are made of the same materials as the green sand beaches in Hawaii," said Diane Wooden, a co-author of both papers. ---
