W.J. McCallion Planetarium
(Hamilton, Ontario)

Next Public Show — August 10, 2022
Topic:What's Up in the August Sky?
Introduction: Summer evenings are a great time for looking up into the night sky, especially from a spot away from city lights. But what are we looking at? Are there any astronomical events to look forward to during August? Join us in the Planetarium as we explore what's up in the night sky at this time of year from our perspective in Hamilton. We'll learn about objects we can see with the naked eye - the Moon, some planets, some constellations, and a meteor shower! Then, we'll look deeper into space and learn about objects that are above us, but can only be seen using a telescope - like other galaxies millions of light years away! We strongly encourage visitors to the Planetarium to wear masks for the duration of the show as the space is small and enclosed.
Show Times:7:00 pm, 8:15 pm
Reserve Tickets:Reserve your tickets and manage your reservations here. Tickets may be available at the door, but this is not guaranteed. If a show is sold out you can choose to be added to the waiting list, and you will be notified if seats become available. Please note that latecomers cannot be admitted and if you are late, your reserved tickets may be given away to those without reservations.

Thank you for your interest in the William J. McCallion Planetarium. We are now once again taking private group show bookings and have resumed our public show schedule on Wednesday evenings. Should you have any specific inquiries or would like to book a show, please reach out to planetarium@physics.mcmaster.ca.

To ensure that we are conducting our reopening plan as safely as possible, we strongly encourage all visitors to the Planetarium to wear masks for the duration of the show as the space is small and enclosed (note: McMaster also strongly encourages visitors to wear masks while inside buildings on campus according to their most recent update).

We appreciate your understanding and flexibility as we continue to adapt to the guidelines laid out by McMaster to ensure a safe reopening. We are privileged that we will soon be able to host you in our space once again. Please direct your concerns and questions to: planetarium@physics.mcmaster.ca.

Sincerely, The McCallion Planetarium team
