CHICAGO – Strong arguments exist for overhauling the lighting systems on U.S. roadways with light emitting diodes (LED), but conversions to improper LED technology can have adverse consequences. In response, physicians at the Annual Meeting of the American Medical Association (AMA) today adopted guidance for communities on selecting among LED lighting options to minimize potential harmful human and environmental effects.
Mounting evidence that artificial light, and newer white light street lighting in particular, is causing measurable harm to wildlife. “This study, the first of its kind, shows that light pollution increases stress hormone concentrations in free-living songbirds. It also suggests that different light spectra may affect physiology differently, thus, using different spectra for street lights may potentially reduce the disturbances caused by light pollution to free-living wildlife.” Read more at http://www.theguardian.com/science/grrlscientist/2015/aug/26/urban-songbirds-stress-hormones-light-pollution
“Georgia MacMillan, a graduate in outdoor education at Galway-Mayo Institute of Technology (Mayo campus) has a dream.” And to help realise her dream of making Ballycroy National Park into a world class Dark Sky Park she has been working with National Parks and Wildlife Service and Mayo County Council, TCD and local residents and businesses to measure the sky quality and make changes to conserve the night sky as a valuable resource in the area.

Following a public talk on light pollution in Lough Gur Heritage Center on Saturday night the Lough Gur Dark Skies Park Initative was launched. Work has already begun on the lengthy process of obtaining official Dark Sky status from the International Dark Sky Association. Despite being only 20km from the centre of Limerick City, we recorded a SQM-L reading of 21.1 during a gap in the clouds. To stay in touch with the initative visit the facebook page at https://www.facebook.com/shannonsidedarkskies Continue reading
Created in 2003 by high-school student Jennifer Barlow, Dark Sky Week has become a worldwide event and a key component of Global Astronomy Month. Each year it is held in April around Earth Day and Astronomy Day. This year celebrations begin Monday, April 13, and run through Sunday, April 19. Continue reading
On Monday 27th of January a packed Ring of Kerry hotel in Caherciveen in Kerry saw the Kerry Dark Sky Reserve receive it’s official Gold Standard status from the International Dark Sky Association. This is the first Gold Tier reserve in the Northern Hemisphere. Continue reading
The 2014 Globe at Night Campaign has kicked off! You can find all details on www.globeatnight.org. All you need to do is go outside, find the constellation of Orion and see which of the sample star charts has roughly the same number of stars as you can see. Whether you live in a dark sky area or in an urban light polluted area completing this survey helps us understand the real amount of light pollution globally.
