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!
Locate the two brightest stars in Orion. Then head northeast from the two brightest stars in Orion about the same distance as the separation between the two brightest stars in Orion. Pollux will be among the brightest star in the sky after Capella and a couple of other stars. Then Castor and Pollux are about two-fingers-together-at-arm’s-length apart from each other. After finding these two stars, the rest of the constellation completes a rectangle toward Orion.
If you are located at a latitude of less than 40°, you will also have the option of using Orion for the February Globe at Night campaign.
Are you passionate about Dark Skies? Consider coordinating an Adopt-a-Street program in your area during the 2020 Globe at Night campaigns.
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.
