Spring Sky over Alberta's Badlands at Dinosaur Provincial Park
Alan: "A 360° and horizon-to-zenith panorama of the spring sky over the badlands at Dinosaur Provincial Park, Alberta, May 25. 2016. I shot this just before moonrise of the waning gibbous Moon."

"Mars is the bright object right of centre, then near opposition and at its brightest. Jupiter is low at far right, setting with Leo into the west. Saturn is dimmer and just left of Mars with Mars and Saturn above Antares in Scorpius in the south. The summer Milky Way is rising across the east and into the southeast at left. The Andromeda Galaxy is just above the horizon at left of centre. The Summer Triangle stars are at centre. Arcturus is at upper right, with Spica and the stars of Corvus near the foreground hoodoo."

"The northern sky at left is brightened with twilight glow, despite this being taken at midnight. At this latitude of 51° north the sky never gets fully dark on late spring and early summer nights."

"One prominent satellite trail, interrupted by the gap between exposures of the frames it was in, is at left, plus the sky has many others! At this time of year they are well lit by the Sun even at midnight."

The horizon is marked by light pollution glows from Calgary (far right) and Brooks (near centre).

The display building for the Trail of the Fossil Hunters trail is at far left.

Dinosaur Provincial Park, Alberta, Canada
www.albertaparks.ca/dinosaur.aspx
Dinosaur Provincial Park is a UNESCO World Heritage Site located about two-and-a-half hours drive southeast of Calgary, Alberta, Canada, or 48 kilometers (30 mi), about a half-hour drive northeast of Brooks. The park is situated in the valley of the Red Deer River, which is noted for its striking badland topography. The park is well known for being one of the richest dinosaur fossil locales in the world.

Badlands are a type of dry terrain where softer sedimentary rocks and clay-rich soils have been extensively eroded by wind and water. They are characterized by steep slopes, minimal vegetation, lack of a substantial regolith, and high drainage density.

Paul: "Happy Birthday Parks Canada! This year marks the 105th anniversary of the establishment of our national park system. Every day I am thankful to live in Canada's first national park, the world's 3rd oldest. I'm curious: what's your favourite national *park?"

"Most people alive today have never seen the Milky Way.

It’s a void that Matt Dieterich, a night sky photographer, has spent his life attempting to fill."

Natalie: "Stargazing in my hometown. Notice the light pollution in the right-hand bottom corner. Although this is a small village with no major industrial areas, the suburban skies are totally polluted."

Video about the damage artificial light is doing to lightning bugs (fireflies).
As lightning bug populations dwindle due to artificial lights, experts ask people to minimize the use of outdoor lights during the beaconing beetles' peak spring and summer mating seasons.

"From any urban or suburban area in Nepal, the night sky is not clearly visible because of the sky glow from various sources of artificial lights from buildings, advertisement boards, neon lights and factories"
Our lives have always been enriched with songs, poems, stories and a myriad of other compositions which depict the beauty and charm of the countless stars

"Lighting in social housing aims for maximum visibility for better CCTV surveillance. Only more affluent neighbourhoods have access to darkness."

"Germany uses far less light than its neighbors and the USA. Despite this, it is a prosperous country that is highly visited by tourists. It has low crime rates (the burglary rate is only 1/3 of that in the brightly lit Netherlands and just over half that of Belgium) and low rates of death due to traffic (about 1/3 less per 1 billion vehicle kilometers than USA or Belgium)."

Story
Tagline
Restore our natural, starry skies by reducing inefficient lighting.
Introduction
The Commission for Dark Skies (CfDS) aims to preserve and restore the beauty of the night sky by campaigning against excessive, inefficient and irresponsible lighting that shines where it is not wanted nor needed.

It was founded in 1989 and is part of the British Astronomical Association (BAA) and affiliated with the International Dark-Sky Association (IDA).

The issues raised by light pollution do not only affect astronomers.  Other areas of concern include crime, the environment and health.

Glare and light spill can make it more difficult to see in the dark. Nocturnal wildlife, such as bats and moths, and plants, eg which use day length to monitor seasons, can be affected. So can migrating birds. Intrusive light can, for example, disrupt sleep.
