Eighty-five percent of the matter in our universe is made up of a mysterious invisible substance scientists call “dark matter.”

This week we're looking for the constellations that make up the Summer Triangle, an easy-to-find asterism in our night sky. We'll also look at a few more objects on the Moon, and if you're feeling adventurous you can try to spot Jupiter and Saturn right next to the Moon too.

We're diving into some more constellations this week! We'll go over Cygnus, Lyra and Aquila, the three constellations that contain the bright stars in the Summer Triangle, and some of the cool objects you can find in those constellations!

It's the Perseids Meteor Shower! This week we will be passing through a cloud of dust left behind by comet Swift-Tuttle, which means we'll have the chance to see shooting stars.

The skies down under (and in South America and Africa) host amazing sights not visible from Canada. We'll use Stellarium to travel to the Southern Hemisphere and see the sights.

Misconceptions are deeply-held beliefs which are incorrect. People have misconceptions about the most basic of astronomical topics, such as the cause of the seasons.

It may surprise you to know that we can still observe the Big Bang, in a way! In fact, every time you accidentally flip to TV static, you're watching a fragment of it right there! To find out more about this echo of the spawning of the universe, join us online on Wednesday, August 12 at 6:30pm. From that first, immense explosion to now, Dr. Adam Hincks will be delving into the details of the cosmic microwave background radiation! As always, everyone is welcome!

This week we are catching the Moon early in its cycle, which means we have the opportunity to spot quite a few craters. We'll be seeking out the diamond ring crater this week!
