The astronomer who was instrumental in ousting Pluto as a planet will tell that story Friday night at the University of Arizona. The debate is still being argued in scientific circles.
Mike Brown, from CalTech, speaks on “How I Killed Pluto and Why it Had it Coming” at 7:30 p.m. Friday at the UA's Integrated Learning Center, Room 120. The talk is free to the public.
