4. The winter Milky Way arches from north (right) to south over the badlands of Dinosaur Provincial Park in a panorama from February 2017 that includes the
glow of Zodiacal Light, caused by sunlight reflecting off dust particles in the inner solar system. It can be seen in the evening early this month and next.

6. Orion and the summer stars of the southern hemisphere set in the moonlight over Loch Ard Gorge on the Great Ocean Road in Victoria, Australia. I shot
this star trail composite in April 2017. This was the site of a famous shipwreck, of the Loch Ard, on June 1, 1878 that only two survived.

8. The Dark Emu rises over the Southern Ocean from the Gippsland Coast of Victoria, Australia. The Southern Cross is at top, while the Magellanic Clouds,
satellite galaxies of the Milky Way, shine at right. The red glow may be airglow or a faint display of Aurora Australis.

10. Back home in Alberta, the northern summer Milky Way arches over the Red Deer River and badlands in a scene from spring 2017. A pale display of Aurora
Borealis lights the northern horizon at left. Bands of red airglow colour the sky at right. The rising summer stars are reflected in the river waters.

12. This composite from June 2017 depicts the Full Moon arcing low across the southern sky, as it does every June. The summer Full Moon traces a path at
night similar to the Sun on a December day, low in the sky. Here, the background sky blends exposures from evening (left), midnight, and dawn (right).

14. The centre of the Milky Way shines low in the south on July evenings from northern latitudes. I shot this scene in July 2017 from Writing-on-Stone
Provincial Park, Alberta. The Milk River winds through the Park’s sandstone formations, with the Sweetgrass Hills of Montana on the horizon.

16. One year ago, on August 21, 2017, the shadow of the Moon raced across the United States, bringing a total eclipse of the Sun to millions of sky gazers. I was
in eastern Idaho, in the Teton Valley where I shot many images of the eclipse which I composited here into a sequence that runs from left to right in time.

18. During the last two years the Moon has been approaching close to and sometimes covering up, or “occulting” the bright star Aldebaran. It did so on the
morning of September 12, 2017 when I shot this image. On September 29 this year the Moon appears close to Aldebaran in the dawn sky.

20. Even in these years of declining solar activity we have been treated to many superb displays of auroras. This was the view on September 27, 2017 from
home in southern Alberta looking straight up at pulsing rays of aurora converging to the zenith, one of the finest sights the sky has to offer.

22. On a night in late December 2016 the planet Venus shines in a clear winter sky over the historic grain elevators at Mossleigh, Alberta. These are among the
few remaining of the original wooden structures that were – and still are – icons of the Canadian Prairies.

24. Might we get a good comet this month? Predictions suggest Comet 46P/Wirtanen might become as bright as magnitude 3 (naked eye) as it moves north
through Taurus beside the Pleiades, as Comet Lovejoy did here in January 2015 when it became a fine photogenic target.
