New Comet Dust Mineral Discovered
Red Orbit ^ | Thursday, June 12, 2008

Posted on 06/13/2008 8:53:29 PM PDT by SunkenCiv

The mineral, a manganese silicide named Brownleeite, was discovered within an interplanetary dust particle, or IDP, that appears to have originated from comet 26P/Grigg-Skjellerup. The comet originally was discovered in 1902 and reappears every 5 years. The team that made the discovery is headed by Keiko Nakamura-Messenger, a space scientist at NASA's Johnson Space Center in Houston... The Earth accretes about 40,000 tons of dust particles from space each year, originating mostly from disintegrating comets and asteroid collisions. This dust is a subject of intense interest because it is made of the original building blocks of the solar system, planets, and our bodies. The mineral was surrounded by multiple layers of other minerals that also have been reported only in extraterrestrial rocks. There have been 4,324 minerals identified by the International Mineralogical Association, or IMA. This find adds one more mineral to that list. The IMA-approved new mineral, Brownleeite, is named after Donald E. Brownlee, professor of astronomy at the University of Washington, Seattle. Brownlee founded the field of IDP research.

WHAT???

Right. All the people on the earth today, all the vehicles, manufacturing plants, etc., etc., and so-on, ad nauseum, produce only about 1% of the carbon dioxide that the Chicken Little Alarmists say will kill the Earth and all of us ASAP!

OK, so maybe my figures aren’t precise. We produce such a negligible amount that the Greenies are scrambling to find ways of making money off thier scare tactics. Sheer idiocy. The REALLY idiotic part is that other idiots are buying into it.

*snark*
