White sky at night not a city bird’s delight

b55fc63c-064e-4273-824d-54acf5c7964c-1020x612Mounting 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

Globe at Night 2014

GLOBE_at_night_logo_200The 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.

Globe at Night 2013

GLOBE_at_night_logo_200The 2013 Globe at night event takes place this year from April 29th to May 8th. We’d encourage you to take part – their website has all the details! All you need to do is compare the sky that you see at your location with the charts on the website to get an estimate of your light pollution. Your reading will then be used to provide a global map of light pollution.
