The Edge of the Backyard: Mapping the Boundaries of the Solar System

April 28, 2023
7:00 PM - 9:00 PM
Pupin Hall, 538 W. 120 St., New York, NY 10027 301

Join us in Pupin Hall 301 on Friday, April 28, at 7:00pm for our final public astronomy event of the 2022-2023 academic year!   


Columbia Astronomy PhD student Ben Cassese will be giving a public talk titled "The Edge of the Backyard: Mapping the Boundaries of the Solar System":

"Despite its relative proximity compared to other treasures of the night sky, the edge of our solar system has only started to come into focus in the last few decades. We've only now started to map out our borders -- and there are hints there is much more to find. What do we know of so far, and what might still be out there?"


We'll kick off the evening at 7:00pm with some astronomy trivia, followed by Ben's talk and Q&A. From 8:10-9:10pm, we will be outside stargazing on College Walk (weather permitting).


This event is free and open to all -- stay only as long as you want. If you plan to attend this event, please fill out the RSVP form at


We look forward to seeing you in Pupin Hall on April 28!
