The night sky is a wondrous canvas, and the summer of 2026 promises a celestial spectacle like no other. From eclipses to meteor showers, the heavens will put on a show that will leave you in awe. So, mark your calendars and prepare for an unforgettable journey through the cosmos. Let's dive into the details of these extraordinary sky events and explore what makes them so captivating.
The Summer Solstice
The summer solstice, occurring on June 21, 2026, at 8:25 UTC, marks the beginning of northern Astronomical Summer. It's the day when the Sun reaches its highest point in the sky, casting its longest shadows of the year. But what many people don't realize is that the longest day of the year isn't just about the amount of daylight. It's about the unique timing of sunrise and sunset, which can vary depending on your location in Canada.
In Atlantic Canada, cities like Sydney, N.S., and Moncton, N.B., have their longest days on June 20 and June 21. Similarly, Granby and Montreal in Quebec, as well as Ottawa, Peterborough, Hamilton, Kitchener, Guelph, London, North Bay, Sault Ste Marie, and Thunder Bay in Ontario, experience their longest days on both dates. In the western half of the country, Gimli and Flin Flon, Man., have their longest days on both the 20th and 21st, despite communities to the north and south having it only on the 21st. This phenomenon is a result of the Earth's slightly elliptical orbit around the Sun, creating a unique interplay of daylight and darkness.
The Planets
The planets put on a dazzling display throughout the spring and summer of 2026. Venus, Jupiter, and Mercury will be visible in the evenings, alongside the bright stars Pollux and Castor of the constellation Gemini. Mars and Saturn, on the other hand, will rise in the morning before sunrise. As the season progresses, Mercury and Jupiter will get closer to the horizon each night, eventually disappearing in evening twilight. Venus will track towards the southwestern sky, while Mars and Saturn will rise earlier and climb higher into the sky by the time the Sun crests the horizon.
The planets will also put on a show in mid-August, with Jupiter and Mercury forming a close conjunction in the predawn sky. This pairing will be easier to spot with binoculars or a telescope, as it will crest the eastern horizon around 5:15 to 5:20 a.m., local time. However, morning twilight will make it challenging to see, so early risers will be rewarded with a celestial spectacle.
The Moon
The summer of 2026 will be marked by three Full Moons, each with its own unique timing. The Full Strawberry Moon on June 29-30, the Full Buck Moon on July 28-29, and the Full Sturgeon Moon on August 27-28 will all shine in our skies. The timing of these Full Moons sets the stage for some excellent astronomical events, particularly in August.
Earth at Aphelion
As Earth travels around the Sun, it doesn't trace out a perfect circle. Instead, it follows an elliptical orbit, with perihelion occurring in early January and aphelion in early July. For 2026, aphelion will take place on July 6, at 1:31 p.m. EDT, with Earth roughly 152,087,777 km away from the Sun. This is an important event to note, as it sets the stage for the upcoming solar eclipse.
Solar Eclipse!
On August 12, 2026, the Sun, the New Moon, and Earth will line up perfectly to produce a total solar eclipse. The Moon will completely block the Sun for up to 2 minutes and 18 seconds, creating a breathtaking spectacle. However, unlike the April 2024 solar eclipse, the path of totality for this event does not pass over any part of Canada. Instead, it tracks from the Arctic down through Greenland, Iceland, the Atlantic Ocean, Portugal, and Spain, before ending in the Mediterranean Sea.
Most of Canada will experience a partial solar eclipse throughout the day, with the magnitude of the partial eclipse varying depending on your location. The best viewing opportunities will be in locations on Ellesmere Island and Baffin Island, coastal regions of Labrador, and along the northern and eastern shores of the island of Newfoundland. However, as there is no safe time to view this eclipse from across Canada without eye protection, be sure to use your eclipse viewing glasses to watch this event.
Perseid Meteor Shower
The Perseid meteor shower, one of the best in the dozen or so significant meteor showers throughout the year, will peak on the night of August 12-13, 2026. Every year, from mid-July through late August, we cross the debris stream of a comet named 109P/Swift-Tuttle, which is the source of the Perseid meteor shower. The shower typically produces between 75-100 meteors every hour during the night of its peak.
The Perseids are known for producing the greatest number of exceptionally bright meteors, known as fireballs. These meteors can be easily seen even from the densest urban centres and are often witnessed by people hundreds of kilometres away. The radiant of the Perseid meteor shower can be found in the northeastern sky after sunset, climbing higher throughout the night. The meteor shower begins on or around July 17 and ends around August 24, with the number of meteors ramping up from a few every night to up to 100 or more per hour by the night of the peak.
Mercury-Jupiter Conjunction
By mid-August, Jupiter and Mercury will have swung around the Sun from us and will be rising in the east, predawn. On the morning of August 15, the two will be very close together, forming another planetary conjunction. This pairing will be easier to spot with binoculars or a telescope, as it will crest the eastern horizon around 5:15 to 5:20 a.m., local time. However, morning twilight will make it challenging to see, so early risers will be rewarded with a celestial spectacle.
Partial Lunar Eclipse
Roughly two weeks after the August 12 Partial Solar Eclipse, the Sun, Earth, and the Full Moon will again line up, causing the Moon to pass through Earth's shadow. This will result in a Partial Lunar Eclipse. Given reasonably clear skies, all of Canada will be able to see most of this eclipse, including the Maximum Partial Eclipse, where the Moon will be roughly 93% immersed into Earth's dark umbra.
The Galactic Core
Summer is an excellent time of the year to spot the bright core of our home galaxy. The Milky Way is visible as a faint band of hazy light arching across the sky all night. You just need to be under dark skies away from bright city lights to see it. The galactic core is visible in our skies throughout much of summer, and you don't need to travel to the Atacama Desert in northern Chile to experience it. A trip out of the city, to get out from under urban light pollution, and a bit of time to let your eyes adjust to the dark, might be all you need. Also, look up your local chapter of the Royal Astronomical Society of Canada and check out any star parties they have on their calendar of events.
Fall Equinox
On September 23, at 00:05 UTC (8:05 p.m. EDT on the 22nd), the Sun crosses the celestial equator headed from north to south, marking the fall equinox and the beginning of Astronomical Autumn for the northern hemisphere. Fall is known as meteor shower season, and for good reason. Of the dozen major meteor showers we see each year, over half take place during this season. In fact, starting in early October, there's at least one meteor shower active each night until the season ends on the Winter Solstice!
