Science News : Michael C. Kelley, an atmospheric physicist at Cornell University, and his colleagues suggest in the July 28 Geophysical Research Letters that data gleaned from analyses of high-flying clouds formed by the space shuttle after takeoff, as well as knowledge about the speed at which shuttle exhaust wafted to polar regions, now hint that the Tunguska blast of June 1908 resulted from a comet slamming into Earth’s atmosphere.
