Hello Folks, Sky & Telescope: Special Moon Issue
A breathtaking close-up view of Tycho on p. 21 - you feel like being there right next to it! An equally breathtaking close-up view of lunar far-side crater Antoniadi on p. 24. Unfortunately, less spectacular, a photo of a Millbillillie specimen on p.54 regarding Vesta: "Vesta is a prime binocular target this winter and spring." The descriptive text says: "Both (= Vesta and Millbillillie) are made of the volcanic mineral pyroxene, a substance that makes Vesta ... unique" Hmm, why should pyroxene make Vesta "unique" among the asteroids? Eucrites are plagioclase- and pigeonite* bearing basalts or gabbros. Pyroxene*, olivine and plagioclase are common constituents of several meteorite classes. *pigeonite = Ca-poor clinopyroxene Best wishes from Germany, Bernd ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
