Asteroids, galaxies, aliens, and space travel...we cover it all on this edition of River to River. Renowned astrophysicist, Neil deGrasse Tyson, joins us to weigh in on all things cosmic.
He will be in Iowa on Monday, April 15, for a lecture at the Iowa Memorial Union in Iowa City. The lecture begins at 7:30 p.m. and is free and open to the public.
