What would it be like without stars at night? What is it we lose?
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.
