Starry night skies have given us poetry, art, music and the wonder to explore. A bright night sky (aka “light pollution”) affects energy consumption, health and wildlife too.
Spend a few minutes to help scientists by measuring the brightness of your night sky. Join the GLOBE at Night citizen-science campaign! The first campaign starts January 3 and runs through January 12.
GLOBE at Night is a worldwide, hands-on science and education program to encourage citizen-scientists worldwide to record the brightness of their night sky. During five select sets of dates in 2013, children and adults match the appearance of a constellation (Orion or Leo in the northern hemisphere, and Orion and Crux in the southern hemisphere) with seven star charts of progressively fainter stars. Participants then submit their choice of star chart with their date, time and location. This can be done by computer (after the measurement) or by smart phone or pad (during the measurement). From these data an interactive map of all worldwide observations is created.
Over the past 7 years of 10-day campaigns, people in 115 countries have contributed over 83,000 measurements, making GLOBE at Night the most successful, light pollution citizen-science campaign to date. The GLOBE at Night website is easy to use, comprehensive, and holds an abundance of background information. Guides, activities, one-page flyers and postcards advertising the campaign are available. Through GLOBE at Night, students, teachers, parents and community members are amassing a data set from which they can explore the nature of light pollution locally and across the globe.
There are 5 GLOBE at Night campaigns in 2013:
January 3 – 12
January 31 – February 9
March 3 – 12
March 31 – April 9
April 29 – May 8
Make a difference and join the GLOBE at Night campaign.
Guest post by Dr. Constance E. Walker, director of GLOBE at Night
Have you ever seen the Milky Way from where you live? Most of us have not, and it’s largely due to increased light pollution from outdoor lighting. Light pollution not only wastes billions of dollars a year in energy and money but it causes human sleep disorders and disrupts habits critical to ecology.
Globe at Night is an international star-hunting campaign that needs volunteers to record their observations of particular constellations in order to measure light pollution. This year’s campaign runs from February 21 through March 6, 2011.
Last year, citizen scientists contributed 17,800 observations and raised awareness about the issue all over the world. The project takes just a few minutes of your time to measure sky brightness and contribute those observations online. Those of you that are tech-savvy can contribute in real-time via the Globe at Night web app. Out of this world!
Contributing to Globe at Night is as easy as pie:
1. Find your latitude and longitude.
2. Find Orion by going outside an hour after sunset (about 7-10pm local time).
3. Match your nighttime sky to one of the project’s magnitude charts.
4. Report your observation.
5. Compare your observation to thousands around the world.
Be a star! Join Globe at night!
