Where there is water, there is life—and Europa’s got water alright: scientists believe it has twice the volume of Earth’s oceans swirling beneath its kilometers-thick ice crust. A moon in Jupiter’s massive orbit, Europa has captivated astrophysicists, including Neil deGrasse Tyson, because it has completely blown open the borders in the search for life in our universe. Europa is well outside of the life-supporting "Goldilocks Zone". Tyson explains how liquid water can exist in such a frozen part of our solar system, and how engineers might approach getting through all that ice to potentially come face to face/membrane with life, whether simple or complex. It won’t be too long before NASA’s ‘Europa Clipper’ mission makes its move to investigate the habitability of the icy moon: it will head for Europa in the 2020s. Tyson's new book is Astrophysics for People in a Hurry.
