Astrobiology, formerly known as exobiology, is an interdisciplinary scientific field concerned with the origins, early evolution, distribution, and future of life in the universe.Astrobiology considers the question of whether extraterrestrial life exists, and if it does, how humans can detect it.. Astrobiology makes use of molecular biology, biophysics, biochemistry,chemistry, astronomy

The Astrobiological Copernican Strong limit is that life must form between 4.5 to 5.5 billion years, as on Earth, while the weak limit is that a planet takes at least 4 billion years to form life, but it can form anytime after that, the researchers said. Intelligent civilisations 2020-06-18 · There may be more than 36 intelligent alien civilizations in the Milky Way, scientists say. By Sophie Lewis June 18, 2020 / 7:30 AM / CBS News The Astrobiological Copernican Strong limit is that life must form between 4.5 to 5.5 billion years, as on Earth, while the weak limit is that a planet takes at least 4 billion years to form life, but it can form anytime after that, the researchers said.
