Globe at Night is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure & submit their night sky brightness observations. It's easy to get involved - all you need is computer or smart phone & follow these 5 Simple Steps!
Cygnus the Swan is easy to find as it flies south along the path of the Milky Way. It is easiest to spot by looking straight up and looking for the three brightest stars forming what is known as the Summer Triangle. The bright star in the lower left of this triangle is Deneb, the tail of the swan. By using this star and looking in toward the center of the triangle, you can now spot Cygnus.
The October 2019 campaign is using the Constellation Cygnus. Check out the dates and constellations for our other campaigns during all 12 months of 2019.

Globe at Night’s “Adopt-a-Street” program
Are you passionate about Dark Skies? Consider coordinating an Adopt-a-Street program in your area during the 2019 Globe at Night campaigns. The Adopt-a-Street program has been selected to be part of the International Astronomical Union’s 100th birthday celebration in 2019 under the framework of the IAU100 Global Project “Dark Skies for All”.
What is the Adopt-a-Street Program?
Globe at Night offers a “Call to Action” for those who want to take more measurements during the campaigns. Children and adults can “Adopt a Street” in their town to take visual and possibly sky-brightness meter measurements during the Globe at Night campaigns. The strategy is for people to adopt a different major or semi-major street and take measurements every mile or so for the length of the street (or for as long as they can). The grid of measurements will canvas the town, allowing for research later in comparison to wildlife, health, energy consumption and cost, among other things.
New! A light pollution education kit: Turn on the Night!
Based on the Quality Lighting Teaching Kit developed by the National Optical Astronomy Observatory for the International Year of Light, 2015, Turn on the Night, a Light and the Environment STEM Kit is available now at Laser Classroom.
Four hands-on activities invite students in grades 7-12 to plan, design and create strategies for city lighting that balance the competing concerns of humans and the environment. Using the problem solving process, students learn about issues raised by human created lighting: Glare, Sky Glow, Light Trespass and Excess Energy Consumption.
