Astrobiology (general): February 2019

Are you an early-career astrobiologist? Would you be interested to contribute to an Astrobiology primer? The first primerwas published in 2006 and second was published in 2016. Now, we are working on the third edition which be hosted as a living document in a NASA-sponsored website.

When we think of life on Earth, we might think of individual examples ranging from animals to bacteria. When astrobiologists study life, however, they have to consider not only individual organisms, but also ecosystems, and the biosphere as a whole.
