In A Sand County Almanac, Aldo Leopold noted that “we can be ethical only in relation to something we can see, feel, understand, love, or otherwise have faith in.” To create conditions for the evolution of a night sky ethic, we need to protect what we have. We need to expose as many people as we can to the stars; we need inspire and educate. We need to create the foundation for a sense of empathy toward the night sky and the people and animals affected by its loss. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1606438297571-I4Q1WNTJDPSLIC71CPLJ/Version+-3b+sig.jpg Home - New Image: Tadpoles and Flaming Star Nebulae The Tadpoles, the blue area in the lower right, is a dusty emission nebula located in the constellation of Auriga at about 12,000 light years from Earth. It's part of a larger star forming region that also contains the Flaming Star Nebula shown here in the upper left of the image. According to NASA, “This Tadpole region is chock full of stars as young as only a million years -- infants in stellar terms -- and masses over 10 times that of our sun. It is called the Tadpole nebula because the masses of hot, young stars are blasting out ultraviolet radiation that has etched the gas into two tadpole-shaped pillars.” The Flaming Star nebula lies about 1,500 light-years away from Earth and is about 5 light-years wide https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1605893338440-0A49Z1E1DYAP9TVIIWT7/Version%2B2%2Bbrighter.jpg Home - New Image: The Spaghetti Nebula The Spaghetti Nebula. That really is the common name for this object. It's also goes by the much more boring names of Simeis 147 and SH2-240. It is an extremely faint supernova remnant located about half way between the constellations Auriga and Gemini. The remnant is pretty big with a diameter of approximately 3 degrees. That's the width of 6 full moons. It's located about 3000 light-years away. The supernova that created the spaghetti nebula occurred about 40,000 years ago. All that's left is a spinning neutron star known as a pulsar surrounded by the intricate filaments of gas and dust seen in the image. The material in this nebula is still expanding at a rate of nearly 600 miles per second. At that speed, you could travel from New York to Los Angeles in 4.085 seconds! https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1607008111624-1SLVAJXLH51HD7KXDIYV/Mt+Lion+NPS.jpg Home - New Article Review: Light pollution alters mountain lion behavior: But not in the way you might think On January 14, 1991, Scott Lancaster, 18, left for a trail run on a rocky hillside above his Idaho Springs high school. He was never seen alive again. A few days later his body was found about a half mile away. A 100 lb mountain lion was spotted nearby. Scott had become the first confirmed mountain lion fatality in Colorado history. Solving the puzzle of Scott’s death requires an understanding of a complex network of social and ecological factors that developed over many decades. A recent study adds a new piece to this puzzle: light pollution. Learn more about how light pollution affects mountain lion behavior, possibly resulting in more encounters with humans. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1607537324821-CROBOPG0I7GIV9OUF2UR/Version+3b+spike+sig.jpg Home - New Image: NGC 7822 The official name for this object is NGC 7822. Common names are by far much more interesting and fun than catalogue entries. It's like looking for shapes in clouds on a summer day. In fact it's exactly like that. Except that these clouds are made of hydrogen, oxygen, sulfur and other gases and they're many trillions of miles in diameter. NGC 7822 is one of those nebulae that does not have a common name. Some people see a flaming skull (that seems pretty dark), while others see a bell. If you rotate it clockwise 90 degrees it kind of looks like a question mark. Personally, in the rotated version I see a giant ear, with a small round earring hanging below it. I'm not sure what that says about me?!

It covered the entire front range of the Rocky Mountains and spread east over Denver on its way to Chicago, Pittsburgh, and the east coast. Meanwhile about 50 miles north, my brother in law and his wife were evacuating, leaving their home in a state of uncertainty and anxiousness. Their small town on the eastern edge of Rocky Mountain National Park was surrounded on three sides by wildfire. The closest, aptly named the east troublesome fire, had started a few days earlier on the west side of the park.

They contributed as much to the creation of your meal as the person running the kitchen. Insects are responsible for pollinating 80% of all trees and bushes on the planet including most of our food. Together, the estimated 5.5 million species form the biological foundation for all terrestrial ecosystems. Unfortunately, insects are in trouble. Recent studies have shown that the abundance of flying insects decreased by more than 80% in the past 20 years and light pollution is a leading cause. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1606162110752-SXG29LKZ2ZOAZ02PGQAE/FinalVersion2a+not+signed.jpg Home - Star Trails: Deep Time, Rythms, and the Night Sky Before cell phones and watches and clocks, humans experienced time by looking up. We watched the movements of the sun, we tracked the motion and phases of the moon, and we studied the stars. Today, as we continue to lose our view of the celestial clock, our connection to the natural rhythm of our lives and our link to the distant past is diminished. Protecting night skies and reducing light pollution can help us maintain, restore, and better understand our ongoing inevitable relationship with time. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1626554510393-A08U8WMWG7XI4CDBHW21/Milky+Way+over+Moab2+copy.jpg Home - Light Pollution and the Greatest Natural Spectacle on the Planet “The sea-bird wheeling round it, With the din of wings and winds and solitary cries, Blinded and maddened by the light within, Dashes himself against the glare, and dies.” — Excerpt from The Lighthouse (1850) by Henry Wadsworth Longfellow April and May are the heart of annual spring migration when birds of all sizes, shapes, and colors work their way to their summer breeding grounds. Lights from cities disorient and divert birds from their route, drawing them in like moths to a flame. Millions won’t survive. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1611952061845-7KJ5YPSNEJKVSDE22AAX/Cali.jpg Home https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1611952272780-NOKYHLVMZASHR5LUVUEZ/Milky+Way+closeup+v10.jpg Home https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1611951903603-2YBRQBFIJ2ZATUB99FQ2/Zooplankton-3.png Home https://www.nightskyresourcecenter.org/light-pollution-research daily 0.75 2021-03-29 https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1612289704277-L2S3Z2TU98ZDUJH7DEUF/protest.jpg Light Pollution Research - Light Pollution and Environmental Justice On September 15, 1982, Dollie Burwell dropped her 10-year-old daughter Kim off at the bus stop, went home, and prepared to be arrested. That morning, 125 people were gathering at the Coley Springs Baptist Church in Afton, NC, steeling themselves to walk the mile and a half to the sight of a hazardous waste landfill where 60 police officers dressed in full riot gear were waiting for them. As she was preparing to leave her house she turned and saw Kim standing at the door. “I want to come with you” https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1607007659234-I7JGEI5AA5PQ0LW89C49/Zooplankton-3.png Light Pollution Research - Light pollution from coastal development can affect seafloor organisms. Roll on, thou deep and dark blue Ocean – roll! – Lord Byron For generation, the seas have been synonymous with darkness. Deep and dark are among the most common descriptors for the oceans. We all know that light gets absorbed quickly by water. We see it when we’re swimming at the beach. At night, we know that below the surface the sea is dark, black, devoid of light. To poets and philosophers, it is the inky depths, the great void. Well, then again, maybe not. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1607007086954-RY5WJ5KJVAQAXO8QCAP5/Mt+Lion+NPS.jpg Light Pollution Research - Light pollution alters mountain lion behavior: But not in the way you might think On January 14, 1991, Scott Lancaster, 18, left for a trail run on a rocky hillside above his Idaho Springs high school. He was never seen alive again. A few days later his body was found about a half mile away. A 100 lb mountain lion was spotted nearby. Scott had become the first confirmed mountain lion fatality in Colorado history. Solving the puzzle of Scott’s death requires an understanding of a complex network of social and ecological factors that developed over many decades. A recent study adds a new piece to this puzzle: light pollution. Learn more about how light pollution affects mountain lion behavior, possibly resulting in more encounters with humans. https://www.nightskyresourcecenter.org/how-you-can-help daily 0.75 2021-04-20 https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1616185132902-UTO977T6GWMZXPREA4U6/LP+Denver.jpg Overview Light pollution, Denver Colorado Photo: F.

As I passed the police on Harrison Ave doing 32 in a 25, I guess I looked suspicious. He pulled me over right in front of Wild Bill’s hamburger joint. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1615918336325-UP3SDTBGUO7VH3E224TG/Logo2name.jpg Overview - Targeted Lighting should be shielded and directed downwards to illuminate only areas that need to be lit. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1615918392035-PY9353EB7WIN3SKEPCQD/Logo2name.jpg Overview - Low Levels Many visual tasks, such as wayfinding, often require fairly low illumination levels. As a result, the minimum amount of light necessary to meet the task should be applied. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1615918311718-Q810S1BLJCWTH44GREKM/Logo2name.jpg Overview - Controlled Lighting may only be necessary at certain times during the night, when an area is in use, or during certain activities and special events. This can be achieved through the use of motion sensors, timers, and other controls. https://images.squarespace-cdn.com/content/v1/5ebee55e8b29b13e1957a810/1615918363293-3Y2CYVD9YXWAPTWH5MAX/Logo2name.jpg Overview - Color. Different light spectra have impacts on visitor experience and park resources and values.
