The search for extraterrestrial life. Astrobiology, a term coined for the study of all life anywhere in the universe (including Earth), has replaced exobiology, the study of extraterrestrial life exclusively and therefore criticizable as “a science that lacks a subject matter.” Unlike exobiology, astrobiology respects the scientific possibility that life beyond Earth may never be found.
astrobiology The study of life everywhere in the universe, including on Earth and in space. atom The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and uncharged neutrons.
Chemical Studies (3)181 In view of these considerations it might seem reasonable to conclude that humankind is at the threshold of an exciting period of extraterrestrial exploration, and therefore our basic concepts of biology may be greatly extended by the discovery of …
Astrobiology is the current term used to encompass the related disciplines engaged in “the study of the living universe,” including the search for extraterrestrial life through in situ exploration, the use of spectroscopy of solar and extrasolar planetary atmospheres, and the perhaps more familiar search for extraterrestrial intelligence.
Humanity is on the verge of discovering alien life, high-ranking NASA scientists say.
1. 1976, The Viking Mars landers detect chemical signatures indicative of life. Tests performed on Martian soil samples by NASA’s Viking landers hinted at chemical evidence of life.
Scientists specialized in space studies state for more than 20 years that, even though there are no conclusive evidences, it is very possible that Extraterrestrial civilizations exist.
A new study has cast doubt on the existence of alien life after discovering that a chemical called phosphorus is less abundant than anyone expected.
