Olivine falling as rain

27 May 2011

At www.jpl.nasa.gov/news/news.cfm?release=2011-161&cid=release_2011-161 ... tiny crystals of a green mineral called olivine are falling down like rain on a star observed by NASAs Spitzer Space Telescope. Astronomers aren't sure how such crystals got to be where they are - but jets of gas are projected as a likely culprit. Olivine was detected by NASAs Stardust and Deep Impact missions as crystals within comets - and olivine is common on the earth.Olivine forms under extreme temperature and its presence in a star that is still in the process of forming is not therefore too difficult for science to suggest - but embryo theories are forming. Ongoing.
