York∞Universe is an Astronomy & Astrophysics program written and presented by the students and faculty of York University in Toronto, Canada.  It broadcasts live each Monday night at 9pm EST / 6pm PST / 0200 UTC from the steps of the York University Astronomical Observatory. The team of hosts includes Paul Delaney, Lianne Manzer, Jesse Rogerson, Harrison Ruess, Ryan Marciniak, and Dr. John Moores. Scroll down to learn more about the hosts.

York∞Universe works in concert with the York Observatory’s Online Public Viewing program (OPV). The OPV program allows you to see images from York’s two telescopes, chat with the observatory’s observing team, and ask questions of the hosts during the live show. You can log into the OPV chatroom at the observatory’s website. (NOTE: The AFM Chatroom is NOT used during York∞Universe).
