Lawrence Rudnick

Astronomer

Lawrence Rudnick and two colleagues, all at the University of Minnesota, are publishing a paper about their discovery of a tremendous void in the cosmos, a billion light year-wide expanse that contains almost nothing. He fills us in, though not the hole, on this week's show. You'll also hear a classic Q&A segment from Emily Lakdawalla, and get a What's Up report and a new space trivia question from Bruce Betts at the Mars Society conference.
