Scientists find bacteria living in polar ice and snow
for the first time in breakthrough that could expand
the zones for habitable planets.Scientists have observed evidence of living bacteria in one of the harshest environments on Earth, where it’s long been thought nothing could survive.Microbial activity in Arctic and Antarctic snow has been directly observed for the first time, revealing bacteria remain active in snow even during the decades-long process of its compression into ice.The discovery could mean bacteria are responsible for slight amounts of CO2 found in air pockets in the polar ice caps – and, it suggests life could thrive in regions or even planets previously considered sterile.
