Announcing a Special Event at the Allan I Carswell Observatory: Jupiter and Saturn - The Great Conjunction of 2020, Dec 21 from 4pm Toronto local time! A conjunction of Jupiter and Saturn only happens about once every 20 years (which is why it is called a great conjunction). Don’t miss out on this great view... Tune into the Allan I. Carswell Observatory’s YouTube page (https://www.youtube.com/user/YorkUObservatory/live) at 4pm on Dec 21, 2020 and enjoy the show!
The observatory is pleased to announce our new STORE, now selling our 2021 Calendar via the York University Bookstore. Enjoy wonderful imagery all year round while supporting the Observatory's activities.   Many of this year's images arise from our new 1-metre telescope! This year, in addition to the calendar, we are also offering fabulous observatory post cards! See the Store link in the menu above or click this image!
