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!

Happy Space Science Saturday! Have you heard of a star trapped within a bubble? Meet NGC 7635, also known as the Bubble Nebula. It is in the Cassiopeia constellation, about 7,100 light-years away from us. Scientists believe this massive star will go supernova in 10-20 million years.
To learn more about the Bubble Nebula check out: https://svs.gsfc.nasa.gov/12247
