Exobiology
Welcome to the Wikiversity Center for Exobiology, part of the School of Biology.
Exobiology, also known as xenobiology or astrobiology, is a speculative field within biology concerned with extraterrestrial life.
The Center for Exobiology is a Wikiversity content development project where participants create, organize and develop learning resources about the search for life beyond Earth.
Where are the data?
[edit | edit source]
Astrobiology is an idea in search of data. Many scientists expect that life is common, probably having come into existence on millions of planets. However, astrobiology is a speculative field within biology; nobody has evidence for extraterrestrial life. Astrobiology includes the concept of artificial life, since any life form with human-like intelligence could conceivably create artificial life in a laboratory. Such artificial life might be more suitable than a biological organism for interstellar travel. While currently funded efforts in astrobiology focus on planetary exploration and attempts to detect planets with Earth-like atmospheres, it has been suggested that we should also look closely at Earth for signs that alien artificial life is already here.
