Once we discover alien life out there, humanity will never be the same.
Finding an alien civilization will change humanity dramatically, but not so much in the obvious ways. Will we interact, trade, learn from one another's technology, or start intergalactic wars? None of that is highly likely, mostly for logistical reasons. Bill Nye thinks that the change will be more of an internal, philosophical, and spiritual change. What will it mean for humans to not be the only living thing in the cosmos? Many of us want to know and so, operating on just a small budget running in the background of all other scientific pursuits, there are astronomers and physicists continually looking and listening for life out there so that we may one day be able to ask ourselves that very question. Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.
Everyone loves Europa, says Neil deGrasse Tyson. Why? It's a strong bet for finding life in our solar system, and it's even more amazing because it breaks all the rules.
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.
