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.
