Welcome to the Alternative Earths Astrobiology Center
Are we alone? Where did we come from? Where are we going? How can we use Earth's history to direct our search for life elsewhere? What did our atmosphere look like before there was oxygen? How can we explain persistent habitation on a dynamic early earth?
These questions get right to the root of what it means to be human, and they are exactly what the science of Astrobiology is all about.
Selected to join the NASA Astrobiology Institute in 2015, the UCR-led Alternative Earths Team explores how Earth has remained persistently inhabited through most of its dynamic history. The idea is to look back in Earth history for direction in our search for life elsewhere—be it Mars, moons of Saturn, or worlds much farther away ...
Building on $12 million in NASA-funded assets at UC Riverside, this cross-departmental integration of Earth science and astronomy—plus a broader array of on-campus collaborations spawned by this alliance—will position the university as a world leader in the search for habitable worlds and life beyond Earth.
