For those of you keeping score at home, we’re celebrating a little anniversary today. This is the 1500th edition of The Best of Our Knowledge. That's over 28 years of TBOOK fun! To celebrate, we’re looking back in our archives, and up to the sky. Today on the Best of Our Knowledge, we’ll talk with Dr. Paul Sutter about cosmic voids, a whole lot of nothing in space.
We’ll also spend an Academic Minute exploring hundreds of small planets.
