Grad Students Boost Astrobiology Hypothesis Browser

For their semester-long science communication capstone project, fifteen Georgia Tech graduate students enrolled in the Astrobiology Graduate Certificate Program published content for Hypothesis Browser, an online tool for hypothesis-based literature searches, designed to capture the state of knowledge around the science of astrobiology and life detection.

Hypotheses were diverse in scope, ranging from planetary formation, to origins of life, to exoplanets, to icy moons, to the evolution of Earth and life. A full list of hypotheses and webpage links is below.

This project was a collaboration between Georgia Tech Astrobiology Graduate Certificate Program, Graham Lau at Blue Marble Space Institute of Science, and Andrew Pohorille at NASA Ames.
