Diatom shells have been found in the Earth’s stratosphere at a height of 27 kilometers. Since there have not been any violent volcanic eruptions in the last three years, the presumption is that they came from space, and probably from inside a comet, according to Professor Milton Wainwright (University of Sheffield, England), who is the lead author of a new paper titled, Isolation of a Diatom Frustule Fragment From the Lower Stratosphere (22-27 km) – Evidence For A Cosmic Origin (Journal of Cosmology, 2013, Vol. 22, pp. 10183-10188). Here’s how the report’s Abstract summarizes the discovery: Sampling of the stratosphere at heights between 22 and 27 km was carried out in the UK on 31st July 2013 using balloon-borne equipment Read More ›
