The LRC Presents…

Ghostly Messengers

A leading astrophysicist explains the pervasive, invisible particles key to understanding our cosmos.

Every second of day and night, many trillions of neutrinos pass through your body.

Luckily, these shadowy particles – celebrated in a delightful John Updike poem and (implausibly) blamed for triggering the apocalypse in a Hollywood disaster flick – do no harm and leave no trace. Yet neutrinos allow us to peer deep into the Sun’s scorching heart, explore the fiery death throes of mighty stars, and unravel the inner workings of our planet. Someday they may even help prevent nuclear proliferation right here on Earth.

Join us for a fascinating discussion of the far-reaching lessons from research into this fundamental feature of the universe.


This event is available free to LRC subscribers or to all those who sign-up for our special event subscription offer of $49 for one year of the LRC. Otherwise tickets are $10 for the general public or $5 for students with a valid ID. Tickets can be purchased or reserved here.


Ray Jayawardhana is a professor and Canada Research Chair in Observational Astrophysics at the University of Toronto, where he also serves as the Senior Advisor to the President on Science Engagement. His new book, Neutrino Hunters: The Thrilling Chase for a Ghostly Particle to Unlock the Secrets of the Universe, was just released by HarperCollins in Canada.

A graduate of Yale and Harvard, he has co-authored over one hundred papers in scientific journals. His discoveries have made headlines worldwide and led to numerous accolades such as the Steacie Prize, the Rutherford Medal, and the Radcliffe Fellowship. He is an award-winning writer whose articles have appeared in The Economist, The New York Times, The Globe and Mail, Scientific American, Astronomy, Muse, and more. His last book, Strange New Worlds: The Search for Alien Planets and Life Beyond Our Solar System, was a finalist for the Lane Anderson Award and the basis of the Planet Hunters television documentary on the CBC. Jayawardhana is also a popular speaker and a frequent commentator for the media.
