Starfest explores the spectacular mysteries of our cosmos on a gigantic scale.  Adventure to supermassive black holes, billions of times as massive as our sun, and discover supernovas and gamma ray bursts, the most luminous and dynamic explosions known.  Powerful solar storms blast from the Sun’s surface in enormous solar flares and coronal mass ejections spew particles into the solar wind that can result in harmful and disruptive geomagnetic storms or simply delight us with colourful, playful auroras.  Colossal galaxies amaze us with their sheer size and complexity.  With the next generation of giant telescopes, both radio and optical, we will investigate deeper into our fascinating cosmos with higher resolution and sensitivity.

At this year’s Starfest, we will learn about the revolutionary Atacama Large Millimeter/submillimeter Array (ALMA), the largest astronomical project in existence.  Updates on the Thirty Meter Telescope (TMT) project will be presented, which upon completion, will become the most advanced and powerful optical telescope on Earth.  We will also celebrate the 2015 Nobel Prize in Physics co-award to the scientists at the Sudbury Neutrino Observatory.

This is an exciting Starfest experience you won’t want to miss!

Starfest is a camping weekend away from city lights, and is not well suited for those on a day trip.
