Look up at the nighttime sky and what do you see? If you're like most, the answer is probably not "stars," but the orange wash of streetlights reflected in the sky above.
Light pollution from ambient nighttime lighting is an unrelenting drain on energy reserves worldwide, and a problem that's growing at a rate of four percent annually. The consistent glare of illumination can adversely affect everything around it, including ecosystems and wildlife.
But at the Mount John Observatory in New Zealand, star-gazers can enjoy a crystal-clear view from Earth of the solar system above, due in part to the nearby township of Lake Tekapo, which increasingly powers down its ambient lights at night.
The observatory is part of a territory that was officially named an International Dark Sky Reserve in 2012, allowing guests to enjoy soaring and detailed views of the universe that we often forget our planet is a part of.

This is not a time lapse. This moonrise, Wellington, New Zealand was recorded and shown in real time is positively spellbinding. The mood music adds a lot to it.

(6,719 posts)Always good to know there are dark places left where we can see these! I go to a local planetarium several times a year to be reminded of the sky the way it is.

having grown up in rural Michigan, the star-filled sky was an inspiration for me to consider my place in the cosmos.

Here are some notes I made on it at the time --
As for what you are talking about -- security lighting -- I remember the film near the end discusses Bar Harbor, Maine passed an ordinance to allow only certain kinds of outdoor night lights -- ones that illuminated in a general downward direction -- not wastefully upward. Anyway, it made a very big difference to night sky viewing.

(10,904 posts)Certainly to take the extreme case, comparing a person standing at the north pole compared to standing at the south pole -- they are both upside down from the other person's perspective. And looking at a distant object, the moon, what is at the "top" of one's field of vision will be at the "bottom" of the other's field of vision. I was trying to see if I could see the familiar rabbit churning butter.
The latitude of Wellington, New Zealand, where the moonrise was video'd, is 41.8 deg S. Compare that to someone like me in Minneapolis at 45 deg N. and we're standing with an angle between us of nearly 90 degrees (right angle). And therefore...
While I was at it, FWIW, I found that the latitude of the Mount John University observatory in New Zealand (where the first video was filmed) is 44.0 deg S.

Magnificent Milky Way Glows Over Machu Picchu (Photo)
by Nina Sen | July 19, 2013 03:00pm ET
The glowing arc of the Milky Way points to the great ruins of the Incan Empire, Machu Picchu, in this vivid night sky image.
Thomas O'Brien took this photo in early July 2013 from the summit of Putucusi Mountain, which is located across the Urubamba River Valley from the historic sanctuary of Machu Picchu, Peru. The UNESCO World Heritage Site is the dark, saddle-shaped area between mountains on the right side of the image where the arc of the Milky Way intersects with the horizon.
The Milky Way, our own galaxy containing the solar system, is a barred spiral galaxy with roughly 400 billion stars. The stars, along with gas and dust, appear like a band of light in the sky from Earth. The galaxy stretches between 100,000 to 120,000 light-years in diameter.
