1. Spotting Six Planets at Dawn

Best time: Before sunrise on August 12, 2026

On August 12, early risers will have the chance to see a rare alignment of six planets: Jupiter, Mercury, Mars, Uranus, Saturn, and Neptune. They will be arranged along the ecliptic from the eastern horizon to the southwestern sky.

While Mars and Saturn are easily visible, spotting Mercury, Jupiter, Uranus, and Neptune will require binoculars and a telescope. The best viewing window for those in Toronto is approximately 5:33–5:47 a.m. local time.

Observers should note that the planetary arrangement will appear slightly different from day to day, so if weather conditions are poor on August 12, backup observations can be made on August 11, 13, or 14.

2. Capturing the Milky Way

Best nights: August 9–15, 2026

The period surrounding the New Moon is ideal for capturing the Milky Way. With the New Moon on August 12, the dark skies from August 9 to 15 provide excellent conditions for photography. The galactic core will be visible soon after sunset, making it a perfect opportunity for both novice and experienced photographers.

To photograph the Milky Way, a DSLR or mirrorless camera with a wide-angle lens and sturdy tripod is recommended. Begin shooting at a high ISO and adjust exposure times to avoid star trails.

3. The Total Solar Eclipse

Date: August 12, 2026

The total solar eclipse on August 12 is the month's most significant daytime event. The path of totality will be visible across parts of northern Russia, Greenland, Iceland, and Spain, lasting less than two and a half minutes at most locations.

For those outside the path of totality, a partial solar eclipse will still be visible, with varying coverage depending on the observer's location.

Safety During the Eclipse

Always use certified solar viewing glasses and proper filters when observing a solar eclipse to protect your eyes and equipment. Only during totality can observers within the path remove their protective gear.
