In this episode of Space Curious experts help explain what it means to go Interstellar, how do we define the vastness of space and who’s making these decisions. This episode was inspired by David Mostardi, of Berkley, California, who wanted to know if the Voyager spacecraft didn't reach the Oort cloud did it really reach interstellar space? Alive Bowman, New Horizons missions operations manager and Stella Ocker, Cornell University planetary scientist, are this week's guests breaking down this fascinating topic. Original music from Rhein was used for this episode. Learn more about your ad choices. Visit megaphone.fm/adchoices
