Are We Alone in the Universe
In the quest for extraterrestrial life, one huge leap has already been made. Scientific research has shown that living organisms can survive in conditions much different than those that are present on Earth. This is confirmed by the existence of so-called extremophiles-organisms that thrive in conditions lethal for other
