An adult kelp gull (Larus dominicanus) in flight near the Antarctic peninsula in the southern ocean. This is the only gull regularly found in the Antarctic peninsula to a latitude of 68 degrees south.

All of Scorpius, plus parts of Lupus and Ara regions of the southern Milky Way. This area was directly overhead when I took this at about 4:30 am local time on April 6, 2014 from near Coonabarabran, Australia. The head of Scorpius is at top his tail at bottom though you could turn this image any direction and it would be correct as seen in the sky at this latitude, depending on the time of night. But in portrait mode like this north is at top. Along the Milky Way are numerous nebulas, including the False Comet area, the Cat's Paw area, and the colourful nebulas around Antares at top. The dark Pipe Nebula is at left of frame.

This is Comet NEOWISE (C/2020 F3) over the Horseshoe Canyon formation near Drumheller, Alberta on the night iof July 10-11, 2020, taken about 2 a.m. MDT with the comet just past lower culmination with it circumpolar at this time. Warm light from the rising waning gibbous Moon provides the illumination. The comet's faint blue ion tail is just barely visible even in the moonlit sky and low altitude. The glow of summer perpetual twilight at latitude 51.5�8 N still colours the northern horizon despite this being close to the middle of the night.

The Northern Lights on Feb 16, 2015, as seen from the Churchill Northern Studies Centre, in Churchill, Manitoba at 58° latitude, and under the auroral oval. The aurora appeared as skies cleared somewhat during a blizzard with high winds and blowing snow conditions. I shot these from the second floor deck of the Centre, out of the wind and off the ground. Jupiter is at right, the Big Dipper at left.
