This is a spiral galaxy in the constellation Pisces and is believed to be one of the most isolated galaxies known, with no other galaxies for around 100 million light-years in all directions.

Join us for Doors Open Toronto!
Visitors to the observatory will have an opportunity to view our 1-metre and 60-centimetre telescopes, speak with astronomy students, learn what it means to be an astronomer, find out about the latest research and discoveries. There will be guided tours of the building, along with a special Observatory Treasure Hunt.
Smaller portable telescopes will be available for visitor use, weather permitting.

Who doesn't love space? It captures our imaginations and makes us wonder if we are truly alone. This is a great Doors Open option for young visitors and the young at heart.

Visitors should note that there are dim light conditions and stairs-only access (unfortunately no lifts or ramps are available) in the observatory and sturdy close-toed shoes are recommended.
Last admittance will be at 4:30 PM ET.
