Public Events
The Rothney Astrophysical Observatory is a working science facility. We are only open to the public during scheduled programs or events.
Milky Way Nights: July 16 - 19, 2026
See astronomers in their natural habitat, under dark moonless skies. Late night public observing is a unique opportunity to see deep sky objects such as planetary nebula and globular clusters. A new moon on July 14 will create fantastic sky conditions.
Milky Way Nights feature an array of telescopes operated by University of Calgary astronomers and members of the Royal Astronomical Society of Canada – Calgary Centre. Visitors will have the opportunity to look through the telescopes and ask astronomers questions about the universe.
10:00 pm - 2:00 am each night
