Benjamin Dean Astronomy Lecture
Pluto Matters
Monday, May 9 | 7:30 pm
Morrison Planetarium
Professor Renu Malhotra
Department of Planetary Sciences, University of Arizona

Discovered less than 100 years ago, Pluto was first designated as the ninth planet in our solar system, then unceremoniously reclassified as a “dwarf planet,” meaning it cannot clear objects out of its path. This lecture will cover how scientists’ understanding of the history of the solar system has undergone a revolution in recent years, owing to new theoretical insights into the origin of Pluto and the discovery of the Kuiper Belt (in which Pluto exists) and its rich dynamical structure which produced the final solar system architecture that we live in today. Dr. Malhotra will review this new view of our solar system's history, describe the astronomical evidence, and critically assess current theoretical models. $8 members, $10-12 non-members.

General Lecture
The Curious Case of Homo naledi: What We Do (and Don't) Know About Our Newest Extinct Relative
Tuesday May 3 | 7 p.m.
Dr. William Harcourt-Smith
Presented in Partnership with the
Leakey Foundation
Join Dr. William Harcourt-Smith as he explores the significance of Homo naledi, the early human relative recently discovered deep within Rising Star cave in South Africa. This find, consisting of over 1500 fossil fragments, is arguably one of the most important fossil discoveries of the last half century. In this talk, he will discuss what makes Homo naledi so unique, where it may fit within the human lineage, and what consequences this groundbreaking discovery may have for our current understanding of human evolution. $12 members, $15 non-members.

Clair Matzger Lilienthal Distinguished Lecture
Is Earth Approaching a Tipping Point?
Friday, May 20 | 3:30 p.m. with reception at 4:30 p.m.
Dr. Elizabeth Hadly, Paul S. & Billie Achilles Chair of Environmental Biology at Stanford University

Based on a new book written by her and her husband, Professor Anthony Barnosky of University of California Berkeley—titled Tipping Point for Planet Earth—How Close Are We to the Edge?—Dr. Elizabeth Hadly will examine if Earth is on the brink of a societally dangerous tipping point. She will discuss how alarming events such the Zika virus, the migrant crisis, climate change, ISIS, food scarcity, drinking water contamination, and other news seems like a string of unrelated crises, but they are, in fact intimately intertwined. How do we know that planetary tipping points happen? Why are we close to one? What can we do individually to help the world tip in a direction that is good for people and the planet, rather than one that will forever harm both? Free with paid general admission to the Academy.
