January 2026 brings Jupiter to the center stage in our night sky. On January 10th, the giant planet reaches opposition, appearing brighter and larger than at any other time this year (with subsequent oppositions happening roughly every 13 months).

Join us for the next public night!

@westernu.ca Students, join us for a student public night!

You're invited to the next public night at Cronyn Observatory!

Celebrate Cronyn Observatory's 85th Anniversary on Oct 25th! Join us for talks on the Observatory's history, explore artifacts, and observe through telescopes (weather permitting). 8-10pm, FREE admission!

Saturn reaches opposition this weekend (Sep 20-21) – the time when Earth passes directly between the Sun and Saturn, bringing this ringed giant closer to us and making it appear at its brightest. Join us for the public night!

Join us for our last public night of summer 2025!

Join us for the next public night!

Come join us for the next public night this Saturday!

Join us at Cronyn Observatory as astronomy meets chemistry. Charmi Bhatt, an astronomy PhD student, will take you on an astrochemistry adventure, exploring how astronomers become cosmic detectives who use nothing but starlight to decode the chemistry of distant galaxies and star-forming regions.

Join us at Cronyn Observatory on July 26, 2025, for a free public night! 🔭 Explore our historic dome, enjoy a guided tour, and peer through our telescopes (weather permitting). ❓ Bring your questions for our astronomy team. No registration needed - just drop by for a unique evening under the stars!

This Saturday at Cronyn Observatory, Amanda Papadimos shares her research on ancient impact craters buried beneath Earth's surface – a unique mix of astrophysics & geophysics! 🌌 If skies are clear, we’ll have telescopes ready for stargazing. 🌟 FREE and open to all – no registration required!

This Saturday, July 5th, 2025, join Ariel Chitan as she talks about what happens when three black holes come together, begin their cosmic dance, and potentially merge. - Also, join us for Stargazing (weather permitting)🔭 🌟 This event is FREE and open to all! No registration required.

Join us for the next public night to tour the Observatory and gaze through our telescopes (weather permitting). Hannah Christie will talk about why we need different telescopes, how they work, and the unique cosmic insights they deliver. Admission is free, and no registration is required.

Next public night will be Saturday, June 7th, 8:30 to 11:00 pm. The talk will begin at 8:30pm. You’re also invited to tour the observatory and, weather permitting, look through our telescopes. Admission is free and open to everyone—no registration required.

Next public NIght: Saturday, May 31 • 8:30–11 PM @ Cronyn Observatory 🌙🔭 Free & open to all—no sign-up needed! • Telescope views (Moon craters, weather permitting) • Demos on finding exoplanets & the Universe’s makeup • Talk: “A Cosmic Tango: Hot Stars in Binary Systems” by Rina Rast

Join us for the next public night on May 24th! 🌑 What makes an asteroid “potentially hazardous” versus simply intriguing? 🔭 How do we spot and follow Near-Earth Objects across the sky? 🚀 Which missions and technologies are designed to redirect asteroids?

Join us on Saturday, May 17th, to explore the science of meteor showers. Why do different showers appear at different times of year? How can you spot the best displays? Prof. Margaret Campbell-Brown, an expert in meteor physics, will share her insights and answer your questions.

Join Dr. Kelly Weinersmith for an engaging talk on the future of science and space, inspired by her bestselling book “A City on Mars: Can We Settle Space, Should we Settle Space, and Have We Really Thought This Through?” RSVP here: www.westernconnect.ca/site/Calenda...

Join us this Saturday for Women in Astronomy Night! Celebrate the amazing contributions of women in astronomy and spark curiosity in the next generation of scientists! 🚀🔭 With hands-on activities, trivia, and great prizes, it’s an event you won’t want to miss. Hope to see you at Cronyn Observatory!
