Solar Observing (GO for Saturday)

Join us at the Ontario Science Centre for our monthly Solar Observing on the TELUSCAPE observing pad. This is the area in front of the Science Centre's entrance. We use specialized telescopes that are safe to aim at the Sun. Check our home page on the Friday prior for go/no-go calls as this event is weather dependent.

UofT Planetarium: The Underdogs of the Solar System – Moons, asteroids, comets and other small rocky objects

Showtimes: 7:00pm, 8:00pm, and 9:00pm Often, when we think of the Solar System, we think of the planets and the Sun and nothing more. But what about all the other stuff? There are millions of asteroids in the asteroid belt, tens of millions of objects in the Kuiper belt, and probably trillions of objects in the Oort cloud—not to mention the hundreds of moons and dozens of dwarf planets that are members of the Sun’s extended family.

UofT AstroTour: Using Interstellar Plasma Lenses as Billion Kilometre Telescopes

Fifty years ago, two radio telescopes across Canada were combined to achieve the resolution of a telescope 3000 km across, a technique now known as VLBI. Interstellar plasma lenses bend light from sources like pulsars, creating multiple images of the same source on the sky. When we combine these images in the same way as radio telescope on Earth, we can measure the position and motion of their source. Since instead of being telescopes separated by 3000km these images are separated by billions of km, this results in remarkably high precision.

UofT Scarborough: Guided Solar Walk & Observatory Tour

Spend an evening with the planets at U of T Scarborough! A free event for four nights only. Take a guided tour of our brand new scale model of the solar system that spans our entire campus, with markers representing the planets placed in the exact locations as they would have been on Canada's confederation, July 1, 1867. Next, listen to an engaging talk from one of University of Toronto's astrophysicists.

City Star Party (GO for Tuesday)

Hover above the moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

Open House and Awards Picnic at the E.C. Carr Astronomical Observatory

Toronto Centre members and their families are cordially invited to attend the 19th Annual Carr Astronomical Observatory (CAO) Open House and RASC Toronto Centre Awards Picnic on Saturday, June 24th, 2017. With ample shelter available in the house and observatory, this is a rain or shine event, so plan to be there. It provides a great opportunity to network and socialize with your fellow members.

New Moon - 10:31pm EDT

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.

UofT Planetarium: Imagining the Size of the Universe

Showtimes: 7:00pm, 8:00pm, and 9:00pm There are many misconceptions about our universe, and the most common one is also the simplest – its size. Our universe is much bigger than we imagine it to be, and only through visual aid (such as a planetarium) can one really grasp the true dimensions of it. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.

St. James Town Library: UofT Astronomy: How the cosmos will kill you

The stars of the night sky appear gentle, peaceful and unchanging. But this is a lie. The Universe is a violent and catastrophic place, with dozens of tools at its disposal to wipe out all life on Earth with almost no warning. Astronomers are still only beginning to appreciate the true scope of the dramatic forces that drive the Universe's evolution. With Dr. Bryan Gaensler from the Dunlap Institute for Astronomy & Astrophysics.
