Light Pollution Project Win at BT Young Scientist & Technology Exhibition

Two students from Kenmare brought home two prizes from the BT Young Scientist competition for a light pollution project this weekend. Prof. Brian Espey of the School of Physics provided advice and encouragement for the project which encompassed both measurements in the centre of every major Munster town as well as a model of the light emission based on population estimates.The students, who both have an interest in astronomy and the night sky developed a model which was later turned into an app to predict sky quality for amateur astronomers. Both students plan on attending third level, with Conor interested in Physics and Astrophysics, while Hannah’s interests lie in Earth Sciences.

Well done to Hannah and Conor, and their science teacher, Sarah Abbott!

astro photoThe IAS is organising another astrophotographic exhibition to take place from 11 November until 2 December 2018 in the National Botanic Gardens, Glasnevin, Dublin.

There will be sixty new spectacular sky images on show.

In addition, there will be a focus on light pollution with a special display stand organised by Dark Sky Ireland and a public talk, by Prof Brian Espey, about light pollution on Saturday 1st December at 14.00 at the same venue.

There will also be a presentation, by John Dolan (IAS), about getting started in astrophotography on Saturday 24th November at 14.00.

Weather permitting there will also be a public stargazing event within the grounds of the National Botanic Gardens on Thursday 15th November from 18.00 until 21.00. Watch this page for further details.

Light Pollution talk in Cork

Light pollution campaign to be launched in Cork. A light pollution campaign will be launched at Cork Astronomy Club’s monthly meeting next Monday (13th March). Albert White, Chairperson of Irish Light Pollution Campaign, will talk on campaigning for dark skies. The venue is 8pm, in UCC’s Civil Engineering Building (near UCC’s College Road entrance). Bus routes 205 (College Road) and 208 (Western Road). All are welcome, free admission. Please arrive at least 10 minutes early. More info on

Sleep Survey

Prof. Andrew Coogan is a behavioural neuroscientist who specialises in the field of circadian rhythms, chronobiology and sleep. He is the director of the Chronobiology and Sleep Research Laboratory at Maynooth University. His particular research interest is in how the fields of circadian clocks, immunology and psychiatry may overlap.

To help with his research and to get a better picture of how light affects Irish people we’d really appreciate if you could take part in a sleep questionnaire that he has prepared at

International Dark Sky Week 2017

idaCreated in 2003 by high-school student Jennifer Barlow, International Dark Sky Week has grown to 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 Saturday, April 22 Earth Day!), and run through Friday, April 28 (click here for resources to use during the week).

There will be events held in Mayo Dark Sky Park, more details as we have them! More details at

Why stay below 3000K?

idaThe rapid advancement of LED technology is unparalleled in the lighting industry, which has caused cities and utilities to reevaluate the specifications used for their street and area lighting applications. Early generation LEDs were typically 5000K or higher, which at the time was the upper end of the technology’s capacity for products that remained both economically viable and energy efficient.  Continue reading

Don’t like new “blue” LED street lights? You are not alone.

01216LEDLights-3Around the world streetlights are being retrofitted and replaced with LED lighting. The promise of lower energy consumption, no light spilling upwards, the ability to dim or cut off the lights seem good on all counts. However many installations are using lights that are to bright and “too blue” with a colour temperature of 4000K and above, despite the downsides to visibility and health from such lights.

Here’s a quick roundup of some recent international news from communities who are pushing for lower temperature and less intrusive LED street-lighting:
