The long awaited second edition of the Astrobiology Primer has been published in the journal Astrobiology, and is available to download!

This version is an update of the Primer originally published in 2006 by graduate students and postdoctoral researchers who wanted to provide a comprehensive introduction to the field. The 2016 version contains revised content that addresses the definition of life in scientific research, the origins of planets and planetary systems, the evolution and interactions of life on Earth, habitability on worlds beyond Earth, the search for life, and the overall implications of the astrobiology research. The Primer is intended to be a resource for early-career scientists, especially for graduate students, who are new to astrobiology. However, the publication can serve as a resource for anyone seeking to understand the framework of the field.
