DescriptionThis image shows a Sub-micron, nano meter sized pre-solar grain, isolated using FIB Qunta 3D-FEG, at the Johnson Space Center NASA. The grain is right under the carbon cap on the very top of the pillar shown in the picture. This sample is from a meteorite and the isolated grain showed, which later on experimentally proved, to be a pre-solar grain. This procedure of isolation made it possible to perform NANO-SIMS analysis and later on preparing a thin X-Section for TEM analysis on this really really precious grain. The study helped towards understanding the formation of stars in our galaxy as well as the origin of our own solar system.
