Are we alone? Really, though, in a cosmic sense. 40 years ago the pioneering radio astronomer Jill Tarter co-founded a Bay Area non profit to support humanity searching for life beyond ourselves. We celebrate the SETI – as in, Search for Extraterrestrial Intelligence – Institute’s anniversary and all their contributions to science which, sadly, do not yet include finding aliens. What do you hope SETI finds in its next 40 years?
