BRIEF: 'Pluto killer' Michael Brown speaks at the Adler

March 04--Fans of the former ninth planet might not be so thrilled to hear that astronomer Michael E. Brown is coming to Chicago to speak. The 2010 book by the professor of planetary astronomy at California Institute of Technology is called "How I Killed Pluto and Why It Had It Coming." In the first Kavli Prize Laureate Dome Lecture, Brown, a winner of the 2012 Kavli Prize in Astrophysics, will speak at the Adler Planetarium on solar system evolution, Pluto and other "dwarf planets" and the evidence for a larger object, a potential true ninth planet, out beyond the dwarfs. The talk will be simulcast to institutions in Denver, Peoria (Riverfront Museum) and Tucson, and will be followed by a speaker reception.

7:30 p.m. Thursday at Adler Planetarium; tickets are $10 ($5 students and members) at adler.org.
