Green Meteorite Found In Morocco May Be From Mercury 89
An anonymous reader writes in with news that a meteorite found in Morocco might be from Mercury. "The green rock found in Morocco last year may be the first known visitor from the solar system's innermost planet, according to meteorite scientist Anthony Irving, who unveiled the new findings this month at the 44th annual Lunar and Planetary Science Conference in The Woodlands, Texas. The study suggests that a space rock called NWA 7325 came from Mercury, and not an asteroid or Mars."

Creator of the universe as claimed by adherents of the faith on planet Viltvodle VI. Their legend has it that the universe was sneezed out of the nose of the Great Green Arkleseizure, and they thus live in perpetual fear of the time they call "The Coming of the Great White Handkerchief."

any high speed impact in which the ejecta achieves escape velocity. Fairly easy to do, if you have either a large enough impactor or one moving fast enough (28,000mph is fairly slow yet fast enough to achieve escape velocity even in Earth's gravity influence).
BTW, there are other bodies in the solar system, other than Earth, with active volcanoes. Two examples: Venus and Io. In fact, Io is the most geologically active body in the entire solar system, due solely to its proximity to Jupiter and the fact that there is a thirty Terawatt polar torus connecting the two. Io's volcanoes regularly throw debris into orbit.
