13900394 - Orion and the stars of the winter sky trailing as they set behind and through Turret Arch, in Arches National Park, Utah. I shot this April 6, 2015 after twilight but before the waning Moon rose, so the sky was dark. Illumination is from stars and the sky – no artificial light provided, and the Moon was not up.13898326 - The Full Moon rising on December 22, 2018, the day after the winter solstice, in a perfectly clear sky and over the distant horizon to the northeast over the snow-covered prairie. Some cows are grazing at left! The top edge of the Moon has a green rim and the bottom edge a red rim, from atmospheric refraction. But it made for a Christmas-coloured Moon ornament on the horizon! The dark lunar mare and even the bright rays splashing from Tycho at bottom are visible.13998616 - A panorama of the summer Milky Way from Sagittarius up to Cepheus,over the Southern Alberta Star Party,September 13,2023. The star party is held at a church camp near Elkwater,Alberta in the Cypress Hills. The sky is very dark there! About 80 people attended this year. Most are looking after their astrophoto rigs. The camp has a number of cabins for accommodation and a main service building at centre here.13900602 - The amazing area of the southern Milky Way in Carina and Crux, the brightest part of the Milky Way after the galactic core region. At right is the Carina Nebula, with the Southern Pleiades cluster, IC 2602, below it. The Football Cluster, NGC 3532, is at upper left of the Carina Nebula. At centre is the region of Lambda Centauri, with the star cluster NGC 3766, the Pearl Cluster, above the emission nebulosity. At left is the Southern Cross, with the dark Coal Sack at bottom left of the Cross, with thin tendrils extending to the right. To the left of Alpha Cruxis at the bottom of the Cross is t13899582 - A panorama of NLCs – noctilucent clouds – aka PMCs or polar mesospheric clouds, taken on June 20, 2022 about 11:40 pm MDT, from home in southern Alberta. After many cloudy nights and some clear nights with no NLCs, this was my first sighting since June 1. The bright luminous mesospheric clouds lit by sunlight at high altitude contrast with the dark tropospheric clouds to the left at low altitude.13897964 - The 2016 Perseid meteor shower, in a view looking north to the Big Dipper and with the radiant point in Perseus at upper right, the point where the meteors appear to be streaking from. I shot this on the peak night of the shower, August 11/12 after moonset so the sky was dark and in fact filled with bright airglow, appearing here as bands of green and yellow, mixed with a low-level aurora to the north as well. While it looks like the sky has artificial light pollution, the glows here are natural, from aurora and airglow.71405947 - An atmospheric misty mid-winter view of York Minster's East window after dark, York, Yorkshire, England, United Kingdom, Europe71325750 - Supertrees Lit after Dark Marina Bay Gardens Singapore TV00058670199529 - Dark clouds build over the La Sal mountains after sunset, as seen from near Kens Lake south of Moab, Utah, USA.71325749 - Supertrees Lit after Dark Marina Bay Gardens Singapore TV00056271205081 - Story Bridge and Brisbane city skyline after dark, Queensland, Australia, Pacific71208630 - Disseny Hub Barcelona and skyscraper Torre Agbar illuminated after dark, architect Jean Nouvel, Barcelona, Catalonia, Spain, Europe71205899 - Brisbane city skyline after dark, Brisbane, Queensland, Australia, Pacific71205900 - Brisbane city skyline after dark, Brisbane, Queensland, Australia, Pacific
