OAST Mission

The goal of OAST is to understand how ocean worlds and their biospheres co-evolve to produce detectable signals of a past or present living world, by combining the expertise of a multidisciplinary team.

Signs of Life

What conditions in ocean systems control their habitability, and what are the observable signals of biological activity in present and past ocean worlds?

About Us
