Polar Bear (Ursa maritimus) in fireweed (Epilobium angustifolium) on an island off the sub-arctic coast of Hudson Bay, Churchill, Manitoba, Canada. Bears come to spend the summer loafing on the island and looking for a careless seal or dead whale to wash up. Global warming has shortened their winter so they are increasingly looking for food in the summer.

A panorama of Lake Edith in Jasper National Park, Alberta, on a calm autumn night, looking north to the stars of Ursa Major, the Great Bear, and the Big Dipper in deep twilight. Arcturus is at far left setting in the northwest over Pyramid Mountain, while Capella in Auriga and the stars of Perseus are rising at right in the northeast. This was on a mid-October night when the Big Dipper rides low in the northern sky from this latitude of 53° N.

Polar Bear (Ursa maritimus) on sea ice off the sub-arctic coast of Hudson Bay, Churchill, Manitoba, Canada. Bears come to the coast of Hudson Bay in Fall waiting for the ice to freeze, and looking for a careless seal or dead whale to wash up. Global warming has shortened their winter so they are increasingly anxious as they wait for winter. While they wait, they engage in frequent wrestling matches to determine a mating hierarchy for the breeding season in March and April, and regularly check on the ice to see if it will carry them out to sea.

Comet NEOWISE (C/2020 F3) over the still waters this night of Crawling Lake in southern Alberta. This was early in the evening with the sky still brightly coloured with twilight. The comet was in the southern part of Ursa Major between the pairs of stars called Tania and Talitha. The clouds that were present nicely framed the scene and reflected in the water as well. The comet was too high to be visible as a reflection at this time.

An arc of a Kp-5 aurora over a wheatfield from home in southern Alberta. The panorama takes in the northern stars, from the Big Dipper and Ursa Major at left, to the W of Cassiopeia at top right of centre, with Perseus below Cassiopeia, and Andromeda and Pegasus at right. Moonlight from the waxing gibbous Moon low in the southwest illuminates the scene. Jupiter is rising at far right low in the southeast. This was taken when the display was at its most active. An hour later as it was fading STEVE appeared in a fabulous show.

Aurora reflected in the calm waters of Frame Lake this evening and arching over the Prince of Wales Museum in Yellowknife, NWT, on Sept 5, 2019. The Museum exterior is lit by rippling coloured LED lights that mimic the aurora. The Big Dipper and Ursa Major are above the aurora. The arc of the Lights was brighter earlier on this evening but had faded by the time I got set, but came back somewhat, as I shot here. I shot this from Somba K’e Park.

This wide-field image frames the end stars of the Big Dipper's handle — Mizar at top,and Alkaid at bottom — and to also include in the frame the bright galaxies Messier 101 (at left) and Messier 51 (at lower right,aka the Whirlpool Galaxy). They are small on this image scale but the image serves for a finder chart illustration of the location of these galaxies relative to the Handle. The famous double star Mizar and Alcor is also obvious at top,as is the red giant star 83 Ursa Majoris. The field is 10° x 15°,so wider than binoculars.
