Breaking Discovery: Eighteen species of bacteria found in troposphere (between 8-15 km above the earth)

Microbes  are  said  to be in every part of earth including the hottest (under sea volcanoes)  and coldest (Polar regions) places of earth. What is being studied in Microbiology is those microbes which can be cultured. They constitute less than 1% of the total microbes in the earth.  Can you believe the news that  microbes exist  even in troposphere which is eight kilometres above the earth.  A recent study conducted by Scientists from School of Biology, School of Earth and Atmospheric Sciences, School of Civil and Environmental Engineering, School of Chemical and Biomolecular Engineering of  Georgia Institute of Technology at  Atlanta, USA and Chemistry and Dynamics Branch/Science Directorate, National
