Happy Space Science Saturday! NGC 6946 lies 25 million light-years away and is a face-on galaxy, meaning it faces us, which makes it easy to observe. In the last century, it’s had 10 supernovae (vs. the Milky Way’s 2), earning it the nickname the Fireworks Galaxy!

This weekend brings a total lunar eclipse, but it won’t be visible from Toronto, unfortunately. A lunar eclipse happens when the Earth passes directly between the Sun and the Moon, casting its shadow across the lunar surface. During a total eclipse, the Moon often turns a reddish hue, earning the nickname “blood moon.” The celestial event will be visible for our friends across Asia and Australia and the central and eastern parts of Africa and Europe.
This September Full Moon is also traditionally called the Corn Moon from Native American tribes harvesting their corn around this time.

Happy Space Science Saturday! A rare Black Moon is coming the night of August 22-23, 2025! This seasonal Black Moon is the third new moon of summer, and while you won’t see it (its sunlit side faces away from Earth), its absence means the darkest skies for stargazing. Catch more stars than usual this weekend and enjoy one of the sky’s rare folklore events! Happy Viewing!
