Scientists have made some tremendous advances in recent years. Biologists are discovering that life is not as delicate as we once thought. No matter where on Earth we look, we seem to encounter life. Hardy bacteria that can thrive in the harshest of conditions. From the extreme heat of thermal springs and deep sea hydrothermal vents to the harsh conditions found in nuclear reactors, bacteria and other microbes find a way to prosper. We have exposed bacteria to the harshness of space on the outside of the international space station, only to discover later that the bacteria hadn’t been killed off, but had survived the exposure and were able to grow again upon return to normal conditions.
