Masao Sako Unseen Objects in Our Solar SystemPenn Science Cafe World Cafe Live Upstairs, 3025 Walnut Street

Masao Sako will discuss his research on searching for new objects in the solar system. He will describe efforts to discover objects beyond the orbit of Neptune, some of which contain valuable information about the complicated dynamical history of the system. Dr. Sako will also discuss why astronomers think that there is a massive previously-unseen planet out there, called Planet Nine, and how it might be found.

Expert faculty from the University of Pennsylvania shed light on their research at the Penn Science Café. It's an evening of engaging, stimulating conversation, with a Q&A session following each talk.

DCC Annual Conference: States of Religious FreedomCivil Discourse at Penn Arts and Sciences

What is religious freedom? Can it truly be universal? What are the rights of religious minorities when set against a nation's popular majority? And when religious liberties seemingly conflict with gender and sexuality rights, which should prevail if the conflict cannot be resolved?  

In its 2018 Annual Conference, The Andrea Mitchell Center for the Study of Democracy will address these challenging questions and disucss how the U.S. accomodates, or hinders, religious expression, culture, and the practice of religious freedom.

This year's panelists will include: Lori G. Beaman (University of Ottawa), W. Cole Durham (Brigham Young University), R. Marie Griffith (Washington University in St. Louis), Nadia Marzouki (Harvard Kennedy School), Daniel Philpott (University of Notre Dame), and Winifred Sullivan (Indiana University at Bloomington).

Co-sponsored by the University of Pennsylvania Department of Religious Studies.
