Planet 9 From Outer Space!
On This Episode

Mike Brown
Planetary Astronomer for California Institute of Technology

Konstantin Batygin
Assistant Professor of Planetary Science for California Institute of Technology
Mike Brown and Konstantin Batygin fully expect a new and undemotable ninth planet will be found in the outer reaches of the solar system. The Caltech researchers talk about their findings and much more. Emily Lakdawalla has made a wealth of Chinese lunar lander images much more accessible. Have gravity waves been discovered? Bill Nye hopes so, as he also remembers Apollo 14 moonwalker Edgar Mitchell.
