Neighborhood Lecture Series
Scott Sheppard, staff scientist at DTM, will give a talk titled "Beyond Pluto: The Hunt for Planet X" at 6:30 p.m. on Thursday, May 19, 2016 in the Greenewalt Lecture Hall as part of Carnegie's Neighborhood Lecture Series.
The Kuiper Belt, which has Pluto as the largest member, is a region of comet-like objects just beyond Neptune. This belt of objects has an outer edge, which we are only now able to explore in detail. For the past few years we have been performing the largest and deepest survey ever attempted to search for distant solar system objects. The ongoing search has discovered the object with the most distant orbit known in our solar system and several of the largest known objects after the major planets.
These extremely distant objects are strangely grouped closely together in space, which suggests a yet unobserved planet more massive than the Earth is shepherding them into these similar orbits. Dr. Sheppard will discuss the most recent discoveries at the fringe of our solar system.
Lectures are free, but registration is encouraged. Click here to RSVP.

DTM Weekly Seminar Series
David Bercovici, a professor of geophysics at Yale University, will give a talk titled "Origin of Plate Tectonics" at 11 a.m. on Thursday, 19 May 2016, in the Greenewalt Lecture Hall as part of DTM's Weekly Seminar Series.
Bercovici received his Ph.D. in geophysics and space physics from the University of California, Los Angeles in 1989. His research interests include geophysical and geological fluid dynamics, continuum mechanics, and nonlinear science, self-organization.
Coffee, tea, and a continental breakfast will be served before the lecture at 10:30 a.m.
